  18. Competencies Framework for Civil Engineer in Thailand

    Directory of Open Access Journals (Sweden)

    Phanudej Kudngaongarm

    2012-02-01

    Full Text Available The civil engineering industry now faces with many problems such as poorly planned projects, breach of the delivery date, erroneous budget estimation, uncontrolled system functionality changes, and inappropriate documentation that all lead to the dissatisfaction of clients. One of the main concerns of civil engineering industry is to develop the talent of its human resources, since the quality and innovation of its products and services depend to a great extent on the knowledge, the ability and the talent that civil engineers apply in the development process. A competency framework defines a set of knowledge, skills, and behaviors that professionals must have to excel in their careers. A competency framework facilitates the identification of training needs and guides the design of a professional development program. In this paper we propose a competency framework for civil engineers, whose design is based on the activities and interactions that they perform during the civil development process. Thus, competency framework for civil engineers defines a set of knowledge, abilities and key behaviors, with special emphasis in the soft skills. The organization that adopts this framework must define and integrate the specific competencies needed by for civil engineers to allow them to fulfill their goals.

  5. CIVIL ENGINEERS' ROLES IN PUBLIC WORKS

    Science.gov (United States)

    Murata, Teruaki

    Recently, the public interests are becoming high in the way of executing public works and the future direction of infrastructure development, which raises nation-wide discussion on these issues. How should we make our country's growth strategy for sustainable development? How should we realize the grand design of infrastructure needed for the implementation of such a strategy? It is obvious that further discussions are needed for these challenging questions. With an aim to promote such discussions, this paper reviews the history of public works and the professional practices (or accomplishments) of our great civil engineers, and discusses the future of public works and the roles of civil engineers based on their origin. Further, in this paper, the author, as the chairman of the Public Works Committee of Japan Civil Engineering Contractors Association, introduces the Association's proposal of "realization of an attractive construction industry." However, for its realization, sustainable institutional arrangements under social consensus are indispensable. Also, individual engineer must establish his/her own identity based on sense of social ethics. It is the author's hope that, through these journals, the professional practices of civil engineers will be widely known to the public with objective logics and discussed to achieve social consensus.

    Institute of Scientific and Technical Information of China (English)

    Aftab A. Mufti; Kenneth W. Neale

    2004-01-01

    For more than a century, important civil engineering structures such as bridges, high-rise buildings, dams and marine platforms have contained iron or steel as the reinforcement for concrete or wood (ISIS Canada Strategic Plan, 2000). The useful lives of such structures have often been severely limited by the corrosion of this ferrous component. Much thought has been given in recent years to constructing structures that are lighter, stronger and non-corrosive. These innovative structures are new and for these to be accepted by the engineering community monitoring is mandatory. ISIS Canada has been developing such structures and monitoring them. In this paper, innovative bridge decks that have been implemented is described.

  16. Active IR-applications in civil engineering

    Science.gov (United States)

    Wiggenhauser, H.

    2002-06-01

    Applications of IR-thermography in civil engineering are not limited to the identification of heat losses in building envelopes. As it is well known from other areas of non-destructive testing, active IR-thermographic methods such as cooling down or lock-in thermography improves the results in many investigations. In civil engineering these techniques have not been used widely. Mostly thermography is used in a quasi-static manner. The interpretation of moisture measurements with thermography on surfaces can be very difficult due to several overlapping effects: emissivity changes due to composition, heat transfer through wet sections of the specimen, cooling through air flow or reflected spurious radiation sources. These effects can be reduced by selectively measuring the reflection in two wavelength windows, one on an absorption band of water and another in a reference band and then combining the results in a moisture index image. Cooling down thermography can be used to identify subsurface structural deficiencies. For building materials like concrete these measurements are performed on a much longer time scale than in flash lamp experiments. A quantitative analysis of the full cooling down process over several minutes can reliably identify defects at different depths. Experiments at BAM have shown, that active thermography is capabale of identifying structural deficiencies or moist areas in building materials much more reliable than quasi-static thermography.

    Jaeger, Jean-Marc [SETEC TPI, Tour Gamma D 58, quai de la Rapee, 75583 Paris (France)

    2005-07-01

    SETEC TPI will address the 'Aging' topic of the Dijon Symposium by talking about: aging in civil engineering materials and structures, prevention of aging phenomena, in-operation monitoring of degradations related to aging and compensatory measures required to maintain a good safety level. Works as the Millau viaduct, the EdF skyscraper at La Defense - Paris, the renovation of the Grand Palais of Paris and special structures with Monaco's floating dam as well as the 'number 10' shaped gateway boat at Marseilles are illustrations for the issues discussed. The durability of civil engineering structures has become a major concern for designers. The Millau viaduct is designed for a service life of 120 years, and the Monaco dam for 100 years. Calculation rules have been evolving toward the incorporation of the concept of life cycle, for example, the Eurocodes 2 rules (reinforced concrete). The talk will expose the factors which are being taken into account to delay aging versus structure types. This part will be focused towards materials and corresponding regulations: - Reinforced concrete (coating of reinforcements, opening of cracks, choice of reinforcement types), BAEL and Eurocodes 2 rules; - Frame steel (protection, sacrificial anode), CM66 and Eurocodes 3 rules. New materials will also be mentioned: - Ultra high-performance fiber/concrete, with the example of CERACEM applied at Millau for the covering of the toll area barrier; - Titanium, which is starting to appear in the building trades, as for instance for the Beijing China Opera House shell. The second part of the talk will be devoted to a specific case namely, the 'number 10' shaped gateway bridge, a prestressed concrete structure immersed in the Port of Marseilles, which will be used to illustrate the aging phenomenon in a corrosive environment. We will focus on the types of inspection series performed by the Autonomous Port Authority of Marseilles to check the behavior of

    2013-01-01

    The potential hazard resulting from uncontained turbine engine rotor blade failure has always been the long-term concern of each aero engine manufacturer,and to fully contain the failed blades under critical operating conditions is also one of the most important considerations to meet the rotor integrity requirements.Usually,there are many factors involving the engine containment capability which need to be reviewed during the engine design phases,such as case thickness,rotor support structure,blade weight and shape,etc.However,the premier method to demonstrate the engine containment capability is the fan blade-off test and margin of safety (MS) analysis.Based on a concrete engine model,this paper aims to explain the key points of aero engine containment requirements in FAR Part 33,and introduces the implementation of MS analysis and fan blade-off test in the engine airworthiness certification.Through the introduction,it would be greatly helpful to the industrial community to evaluate the engine containment capability and prepare the final test demonstration in engine certification procedure.

  17. Situated learning methodologies and assessment in civil engineering structures education

    Science.gov (United States)

    Bertz, Michael Davis

    This thesis describes an overarching study of civil engineering undergraduate structural education through student performance in recalling and applying basic structural engineering knowledge, and the viability of alternative situated learning environments for more effectively supporting the learning of this knowledge. To properly ground this study, a thorough investigation of related work in assessment, cognitive science, educational technology, and design education was completed, with connections and applications to civil engineering education highlighted. The experimental work of the thesis is organized into three parts: an assessment of civil engineering undergraduates' fundamental structural engineering knowledge and abilities; the development and testing of a software support environment for situated learning, the Civil Engineering Learning Library (CELL); and, the implementation and evaluation of the design studio, a pedagogical model for situated learning in the classroom. The results of the assessment study indicate that civil engineering seniors (and also students earlier in the curriculum) have difficulty retaining and applying basic knowledge of structural behavior, especially doing so in a flexible fashion in design situations. The survey also suggests that visualization plays an important role in understanding structural behavior. Tests with the CELL system show that a cognitively-flexible multimedia environment can support structural learning, but were inconclusive about whether the computer-based system helped the students to learn better than conventional classroom lecture. Two trial implementations of the design studio indicate that the studio model can serve as a powerful situated learning environment, and that it can be scaled up to reasonable class sizes. Significant requirements are associated with this model, however, primarily in faculty involvement, but also in physical resources and student time. In addition to these conclusions about the

    2012-08-01

    This special issue of Journal of Geophysics and Engineering offers a diverse panorama of approaches and technologies that aim to characterize and analyse the state of conservation and health of cultural heritage and civil infrastructure. In particular, it provides a significant overview not only of the effectiveness but also of the limitations of single diagnostic techniques, which can be overcome through the integration of different methods and technologies and/or the use of robust and novel data processing techniques. The choice of diagnostic strategy depends on the material (concrete, masonry), the spatial characteristics of the objects or sites, the value of the objects to be investigated (cultural or not), the aim of the investigation (knowledge, conservation, restoration) and the issues to be addressed (monitoring, decay assessment, etc). The paper by Fornaro et al reports an important technological advance in the field of slow deformation monitoring of civil infrastructure by means of differential interferometric synthetic aperture radar (SAR) from satellite platforms. The paper shows how the joint exploitation of the last generation of X-band SAR sensors, such as TerraSAR-X, and novel tomographic approaches makes possible advanced multi-dimensional imaging of real structures such as the Las Vegas Monorail. Within the same SAR-based applications, Tapete et al tested the capability of persistent scatterer interferometry (PSI) techniques in the preventative diagnosis of deformation threatening the structural stability of archaeological monuments and buried structures in the Roman Forum, Palatino Hill and Oppio Hill in the centre of Rome. A PSInSAR processing approach, based on the use of the SqueeSAR algorithm, has been shown to be highly suitable for retrieving not only information about displacements of the archaeological remains, but also evidence of criticalities affecting partially or totally buried structures, such as those discovered at Nero's Golden

    Full Text Available Substantial changes, not only in the demographic composition of the Australian workforce, but also,in the roles and expectations of men and women, have led to organisational and employee attempts to reconcile work and non-work demands. Research suggests that when work-family balance practices are introduced they can greatly enhance organisational efficency. However factors embedded in the organisational culture can undermine these policies rendering them ineffective. This quantitative study examined the relationship between the perceptions of a supportive work culture and some work and non-work experiences of Australian male civil engineers. The research investigated the prevalence of organisational values supportive of work-life balances as well as the level of work-family conflict perceived by those engineers. This paper reports some initial results of the study. These indicated that male civil engineers experienced moderate levels of work-family conflict but do not perceive their organisations to be very supportive of employee nneeds to balance work and personal life. However those that reported a supportive work environment also reported higher levels of organisational commitment, greater job and life satisfaction as well as lower level of work-family conflict and lower intentions to quit. The implications of the findings for organisations employing civil engineers are discussed.

  19. LHC Civil Engineering Construction Contracts Cost Monitoring and Budget Forecasting

    CERN Document Server

    Skelton, K

    2000-01-01

    The Civil Engineering project for the LHC is estimated at 350 MCHF, of which about 316 MCHF is for the construction contracts. These contracts are based on a system of remeasurement whereby the consultant estimates the quantities required for the construction of each structure and the contractor commits himself to the unit price, which define the initial tender price. There are many factors that affect the final price for these contracts, from increases or decreases in quantities of the estimated amounts in the original bill of quantities to variations to the contract. This paper will look at how these factors change costs at the individual level of a structure to the overall costs of the contract. It will look at how the Civil Engineering Group monitors these changes to calculate cash flows and final costs and how this information is used as a basis for budget forecasts.

    CERN Document Server

    Watson, T

    2003-01-01

    In April 1996 CERN awarded three contracts for the provision of civil engineering design and site supervision services associated with the LHC Project. These three contracts with an average value at signature of 12MCHF were placed using the “two envelope” award system. Eight firms from six member states were integrated into three Joint Ventures. For Projects prior to the LHC, CERN would have carried out the design and supervision using in-house staff. The change to out-sourced services represented a major step for CERN. After seven years, the contracts are now coming to their conclusion. This paper aims to discuss the reasons why these contracts were originally implemented, the lessons than have been learnt over the last seven years and conclusions on how CERN could approach the need for civil engineering design services in the future.

    Full Text Available The work of Building and Civil engineering demands a greater knowledge, skill and precision in quantity estimation.The manual method of estimating quantities for building and civil engineering works has posed potential problem areas on work that is undertaken. The low reliability of manual estimation indicates discrepancies in the accuracy of quantities computed manually,hence,the introduction of a digital computation.It is envisaged that this method will greatly reduce the complexities of different aspects when computing quantities for projects, as well as reduce the time to complete the computation and therefore projects can be started earlier.The paper reviewed the procedures involved in the development of a computer program for the digital computation of Building and Civil engineering quantities.The program was developed using Microsoft Visual C SHARP (C# programming language and Microsoft Visual studio. The steps/procedure used in achieving the development of the computer program was (1.designing the application interface,(2 adding controls to the window and (3writing codes behind the interface.The digital computation was tested using a proposed Road project and a proposed administrative buildingand the results showed an average of 100% of the items has 0 to 10 percentage difference for the road and 92% for the building in the final outputs of the quantities obtained through the manual computation and the digital computation and the software could therefore be said to be accurate and reliable.

    2013-06-20

    Behavior analysis of construction safety systems is of fundamental importance to avoid accidental injuries. Traditionally, measurements of dynamic actions in civil engineering have been done through accelerometers, but high-speed cameras and image processing techniques can play an important role in this area. Here, we propose using morphological image filtering and Hough transform on high-speed video sequence as tools for dynamic measurements on that field. The presented method is applied to obtain the trajectory and acceleration of a cylindrical ballast falling from a building and trapped by a thread net. Results show that safety recommendations given in construction codes can be potentially dangerous for workers.

  13. Multi-hazard approaches to civil infrastructure engineering

    CERN Document Server

    LaFave, James

    2016-01-01

    This collection focuses on the development of novel approaches to address one of the most pressing challenges of civil engineering, namely the mitigation of natural hazards. Numerous engineering books to date have focused on, and illustrate considerable progress toward, mitigation of individual hazards (earthquakes, wind, and so forth.). The current volume addresses concerns related to overall safety, sustainability and resilience of the built environment when subject to multiple hazards: natural disaster events that are concurrent and either correlated (e.g., wind and surge); uncorrelated (e.g., earthquake and flood); cascading (e.g., fire following earthquake); or uncorrelated and occurring at different times (e.g., wind and earthquake). The authors examine a range of specific topics including methodologies for vulnerability assessment of structures, new techniques to reduce the system demands through control systems; instrumentation, monitoring and condition assessment of structures and foundations; new te...

  14. Geophysical Methods for Non-Destructive Testing in Civil Engineering

    Science.gov (United States)

    Niederleithinger, E.

    2013-12-01

    Many non-destructive testing (NDT) methods for civil engineering (e. g. ultrasonics, radar) are similar to geophysical techniques. They just differ in scale, material under investigation and vocabulary used. In spite of the fact that the same principles of physics and mathematics apply to both fields, exchange has been limited in the past. But since a few years more and more geophysical knowledge is used in civil engineering. One of the focal points in research is to improve ultrasonic testing of concrete to be able to image the inside even of large, complex structures and to detect any deterioration as early as possible. One of the main issues is the heterogeneity of concrete, including aggregates, reinforcement, cracks and many other features. Our current research focuses on three points. One is the application of state of the art geophysical migration techniques as Reverse Time Migration (RTM) to image vertical faces or the backside of voids and ducts in thick concrete structures, which isn't possible with conventional techniques used in NDT. Second, we have started to use seismic interferometric techniques to interpolate ultrasonic traces, which can't be measured directly for technical reasons. Third, we are using coda wave interferometry to detect concrete degradation due to load, fatigue, temperature or other influences as early as possible. Practical examples of the application of these techniques are given and potential future research directions will be discussed. It will be shown, how a subset of these techniques can be used for innovative monitoring systems for civil infrastructure.

  16. Applications of distributed fiber Bragg grating sensors in civil engineering

    Science.gov (United States)

    Nellen, Philipp M.; Broennimann, Rolf; Sennhauser, Urs J.; Askins, Charles G.; Putnam, Martin A.

    1995-09-01

    We report on civil engineering applications of wavelength multiplexed optical-fiber Bragg grating arrays produced directly on the draw tower for testing and surveying advanced structures and material like carbon fiber reinforced concrete elements and prestressing tendons. We equipped a 6 m X 0.9 m X 0.5 m concrete cantilever beam reinforced with carbon fiber lamellas with fiber Bragg grating sensors. Static and dynamic strain levels up to 1500 micrometers /m were measured with a Michelson interferometer used as Fourier spectrometer with resolutions of about 10 micrometers /m for all sensors. Comparative measurements with electrical resistance strain gauges were in good agreement with the fiber optic results. We used the fiber sensors in two different arrangements: some Bragg grating array elements measured the local strain while others were configured in an extensometric way to measure moderate strain over 0.1-1 m.

  3. Assessing the Use of Failure Case Studies in Civil Engineering Education

    Directory of Open Access Journals (Sweden)

    Elleithy Wael

    2016-01-01

    Full Text Available Civil engineering failures, unfortunately, occur from time to time leading to serious consequences. It is of importance that civil engineering undergraduate students are made aware of cases of failure in the past, and hence, to enhance their ability of identification of potential deficiencies. Investigating past cases of civil engineering failures has been carried out in UNMC for the last five years. The students are required to research, investigate and write essays reporting on these failures, detailing the causes and lessons learned. This study was conducted in order to assess the effectiveness of such approach. The outcomes of this study indicate that the use of civil engineering failure as case studies enhances the students’ educational experiences. In addition to the technical learning benefits from past civil engineering failure case studies, there are also impacts on students’ attitudes which has significant implications in their expected profession.

    Muography techniques applied to geological structures greatly improved in the past ten years. Recent applications demonstrate the interest of the method not only to perform structural imaging but also to monitor the dynamics of inner movements like magma ascent inside volcanoes or density variations in hydrothermal systems. Muography time-resolution has been studied thanks to dedicated experiments, e.g. in a water tower tank. This paper presents the activities of the DIAPHANE collaboration between particle- and geo-physicists and the most recent results obtained in the field of volcanology, with a focus on the main target, the Soufrière of Guadeloupe active volcano. Special emphasis is given on the monitoring of the dome's inner volumes opacity variations, that could be ascribed to the hydrothermal system dynamics (vaporization of inner liquid water in coincidence with the appearance of new fumaroles at the summit). I also briefly present results obtained in the fields of civil engineering (study of urban underground tunnels) and archaelogy (greek tumulus scanning).

  5. Civil engineering work to raise the level of Route Goward

    CERN Multimedia

    2013-01-01

    Civil engineering work to raise the level of Route Goward will take place during Long Shutdown 1. The work will begin on 18 March 2013 and is expected to last around 5 months.   Route Goward runs over the top of the PS tunnel and is the only access route to the inside of the ring. The layer of shielding backfill beneath this road is the thinnest anywhere on the PS ring. As the purpose of this shielding is to protect against the ionising radiation emitted by the accelerator when in operation, this road has been classified as a “supervised radiation area” according to radiation protection regulations. This classification was merely a temporary solution and, on the recommendation of the PS Radiation Working Group (PSRWG), the decision has been taken to raise the surface level permanently by around 2 m in order to increase the thickness of the shielding and thus lower the dose rate to that of a non-designated area. As the PS tunnel itself is unable to withstand the weight of t...

  12. Applications and issues of GIS as tool for civil engineering modeling

    Science.gov (United States)

    Miles, S.B.; Ho, C.L.

    1999-01-01

    A tool that has proliferated within civil engineering in recent years is geographic information systems (GIS). The goal of a tool is to supplement ability and knowledge that already exists, not to serve as a replacement for that which is lacking. To secure the benefits and avoid misuse of a burgeoning tool, engineers must understand the limitations, alternatives, and context of the tool. The common benefits of using GIS as a supplement to engineering modeling are summarized. Several brief case studies of GIS modeling applications are taken from popular civil engineering literature to demonstrate the wide use and varied implementation of GIS across the discipline. Drawing from the case studies, limitations regarding traditional GIS data models find the implementation of civil engineering models within current GIS are identified and countered by discussing the direction of the next generation of GIS. The paper concludes by highlighting the potential for the misuse of GIS in the context of engineering modeling and suggests that this potential can be reduced through education and awareness. The goal of this paper is to promote awareness of the issues related to GIS-based modeling and to assist in the formulation of questions regarding the application of current GIS. The technology has experienced much publicity of late, with many engineers being perhaps too excited about the usefulness of current GIS. An undoubtedly beneficial side effect of this, however, is that engineers are becoming more aware of GIS and, hopefully, the associated subtleties. Civil engineers must stay informed of GIS issues and progress, but more importantly, civil engineers must inform the GIS community to direct the technology development optimally.

    The Imperial College of Engineering (ICE or Kobu-Daigakko) in Tokyo, founded in 1873 under the auspices of the Ministry of Public Works, was one of the most prominent modern institutions of engineering education in early Meiji Japan. Previous studies have revealed that the ICE offered large scale practical training programs at enterprises of the Ministry, which sometimes lasted several months, and praised their ideal combination of theory and practice. In reality, it has been difficult to evaluate the quality of education at the ICE mainly because of scarcity of sources. ICE students published a collection of memoirs for alumni members, commemorating the fiftieth-year of the history of the Tokyo Imperial University. Drawing on the previously neglected collection of students' memoires, this paper appraises the education of civil engineering offered by the ICE. The paper also compares this collection with other official records of the college, and confirms it as a reliable source, even though it contains some minor errors. The author particularly uses the memoirs by Ayahiko Ishibashi, one of the first graduates from its civil engineering course, who left sufficient reminiscences on education that he received. This paper, as a result, illustrates that the main practical training for the students of civil engineering was limited to designing process, including surveying. Furthermore, practical training that Ishibashi received at those enterprises often lacked a plan, and its effectiveness was questionable.

  9. Utilization of washery waste as secondary raw materials in civil engineering and other industries

    Energy Technology Data Exchange (ETDEWEB)

    Leonhard, J.; Schieder, T.

    1990-02-01

    Specific demands are put on waste from hardcoal production when used as a substitute for scarcening conventional construction materials such as sand, gravel and road stone. Untreated washery refuse is not useful, in general, except as bulk material for subsoil improvement as well as for the construction of embankments and dikes. By subjecting minestone to appropriate mechanical or thermal treatment aggregates it to serve as construction materials in civil engineering and in other industries can be obtained. Face bricks, compact and perforated blocks as well as large hollow blocks either with a calcareous or a cement binder were manufactured for civil engineering. Crushed coarse minestone proved its usefulness as a concrete aggregate. Utilization of ashes from fluidized bed firing systems yielded construction materials whose low density made them particularly fit for thermal insulation pruposes.

  10. Standard Practice for Evaluating Material Property Characteristic Values for Polymeric Composites for Civil Engineering Structural Applications

    CERN Document Server

    American Society for Testing and Materials. Philadelphia

    2006-01-01

    1.1 This practice covers the procedures for computing characteristic values of material properties of polymeric composite materials intended for use in civil engineering structural applications. The characteristic value is a statistically-based material property representing the 80 % lower confidence bound on the 5th-percentile value of a specified population. Characteristic values determined using this standard practice can be used to calculate structural member resistance values in design codes for composite civil engineering structures and for establishing limits upon which qualification and acceptance criteria can be based. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

    This book describes basic reliability concepts – parametric ALT plan, failure mechanism and design, and reliability testing with acceleration factor and sample size equation. A generalized life-stress failure model with a new effort concept has been derived and recommended to calculate the acceleration factor of the mechanical system. The new sample size equation with the acceleration factor has also been derived to carry out the parametric ALT. This new parametric ALT should help a mechanical/civil engineer to uncover the design parameters affecting reliability during the design process of the mechanical system. Consequently, it should help companies to improve product reliability and avoid recalls due to the product/structure failures in the field. As the improper or missing design parameters in the design phase are experimentally identified by this new reliability design method - parametric ALT, the mechanical/civil engineering system might improve in reliability by the increase in lifetime and the reduc...

  16. Smart Sensing Technologies for Structural Health Monitoring of Civil Engineering Structures

    M. Sun

    2010-01-01

    Full Text Available Structural Health Monitoring (SHM aims to develop automated systems for the continuous monitoring, inspection, and damage detection of structures with minimum labour involvement. The first step to set up a SHM system is to incorporate a level of structural sensing capability that is reliable and possesses long term stability. Smart sensing technologies including the applications of fibre optic sensors, piezoelectric sensors, magnetostrictive sensors and self-diagnosing fibre reinforced composites, possess very important capabilities of monitoring various physical or chemical parameters related to the health and therefore, durable service life of structures. In particular, piezoelectric sensors and magnetorestrictive sensors can serve as both sensors and actuators, which make SHM to be an active monitoring system. Thus, smart sensing technologies are now currently available, and can be utilized to the SHM of civil engineering structures. In this paper, the application of smart materials/sensors for the SHM of civil engineering structures is critically reviewed. The major focus is on the evaluations of laboratory and field studies of smart materials/sensors in civil engineering structures.

    During capital and/or maintenance dredging operations, large amounts of material are produced. Instead of their discharge, dredged sediments may be a valuable natural resource if not contaminated. One of the possible areas of application is civil engineering. In the present work, the environmental status of seaport dredged sediment was evaluated in order to investigate its potential applicability as a secondary raw material. Sediments were analysed for element concentrations in digested samples, aqueous extracts and fractions from sequential extraction; for fluoride, chloride and sulphate concentrations in aqueous extracts; and for tributyltin (TBT). Granulometric and mineralogical compositions were also analysed. The elemental impact was evaluated by calculation of the enrichment factors. The total element concentrations determined showed moderate contamination of the dredged sediments as was confirmed also by their moderate enrichment factors, presumably as a result of industrial and port activities. Elemental concentrations in the aqueous extract were very low and therefore do not represent any hazard for the environment. The water-soluble element concentrations were under the threshold levels set by the EU Directive on the landfill of waste, on the basis of which the applicability of dredged sediments in civil engineering is evaluated, while the content of chloride and sulphate were above the threshold levels. It was found out that due to the large amounts of sediment available, civil engineering applications such as the construction of embankments and backfilling is the most beneficial recycling solution at present.

  18. Civil engineering at the crossroads in the twenty-first century.

    Ramírez, Francisco; Seco, Andres

    2012-12-01

    The twenty-first century presents a major challenge for civil engineering. The magnitude and future importance of some of the problems perceived by society are directly related to the field of the civil engineer, implying an inescapable burden of responsibility for a group whose technical soundness, rational approach and efficiency is highly valued and respected by the citizen. However, the substantial changes in society and in the way it perceives the problems that it considers important call for a thorough review of our structures, both professional and educational; so that our profession, with its undeniable historical prestige, may modernize certain approaches and attitudes in order to continue to be a reliable instrument in the service of society, giving priority from an ethical standpoint to its actions in pursuit of "the public good". It possesses important tools to facilitate this work (new technologies, the development of communications, the transmission of scientific thought.···); but there is nevertheless a need for deep reflection on the very essence of civil engineering: what we want it to be in the future, and the ability and willingness to take the lead at a time when society needs disinterested messages, technically supported, reasonably presented and dispassionately transmitted.

  19. Numerical Prediction of Differences in Micromechanical Fracture Sequence in Notched and Un-Notched Wires for Civil Engineering Applications

    Directory of Open Access Journals (Sweden)

    Adewole, K.K.

    2014-01-01

    Full Text Available The need to employ simulation-based investigations of fracture of civil engineering structures has been emphasised recently in literature. In this paper, three dimensional finite element simulations revealed that the cup and cone fracture process in channel-shaped notched wire for civil engineering applications begins with a slant fracture at the root of the outer edge of the channel-shaped notch and follows a slant to flat fracture sequence. These results demonstrate that the fracture origin in cup and cone fracture in notched wires for civil engineering applications does not necessarily begin with a flat fracture at the center of the wire and does not necessarily follows the flat to slant fracture sequence or propagation generally reported in literature. These results further demonstrate the need to employ simulation-based methodologies in conjunction with or as an alternative to purely experimental fractographic analysis for an accurate failure analysis of wires used for civil engineering applications.

    2013-01-01

    Defining specific engine requirements is a critical part of identifying technologies and operational models for potential future rotary wing vehicles. NASA's Fundamental Aeronautics Program, Subsonic Rotary Wing Project has identified the Large Civil TiltRotor (LCTR) as the configuration to best meet technology goals. This notional vehicle concept has evolved with more clearly defined mission and operational requirements to the LCTR-iteration 2 (LCTR2). This paper reports on efforts to further review and refine the LCTR2 analyses to ascertain specific engine requirements and propulsion sizing criteria. The baseline mission and other design or operational requirements are reviewed. Analysis tools are described to help understand their interactions and underlying assumptions. Various design and operational conditions are presented and explained for their contribution to defining operational and engine requirements. These identified engine requirements are discussed to suggest which are most critical to the engine sizing and operation. The most-critical engine requirements are compared to in-house NASA engine simulations to try to ascertain which operational requirements define engine requirements versus points within the available engine operational capability. Finally, results are summarized with suggestions for future efforts to improve analysis capabilities, and better define and refine mission and operational requirements.

    2014-01-01

    A Large Civil Tiltrotor (LCTR) conceptual design was developed as part of the NASA Heavy Lift Rotorcraft Systems Investigation in order to establish a consistent basis for evaluating the benefits of advanced technology for large tiltrotors. The concept has since evolved into the second-generation LCTR2, designed to carry 90 passengers for 1,000 nautical miles at 300 knots, with vertical takeoff and landing capability. This paper explores gas turbine component performance and cycle parameters to quantify performance gains possible for additional improvements in component and material performance beyond those identified in previous LCTR2 propulsion studies and to identify additional research areas. The vehicle-level characteristics from this advanced technology generation 2 propulsion architecture will help set performance levels as additional propulsion and power systems are conceived to meet ever-increasing requirements for mobility and comfort, while reducing energy use, cost, noise and emissions. The Large Civil Tiltrotor vehicle and mission will be discussed as a starting point for this effort. A few, relevant engine and component technology studies, including previous LCTR2 engine study results will be summarized to help orient the reader on gas turbine engine architecture, performance and limitations. Study assumptions and methodology used to explore engine design and performance, as well as assess vehicle sizing and mission performance will then be discussed. Individual performance for present and advanced engines, as well as engine performance effects on overall vehicle size and mission fuel usage, will be given. All results will be summarized to facilitate understanding the importance and interaction of various component and system performance on overall vehicle characteristics.

    Concrete structures which are encountered at EDF, like all civil engineering structures, age. In order to adapt the maintenance conditions of these structures, particularly to extend their service life, and also to prepare constructions of future structures, tools for predicting the behaviour of these structures in their environment should be available. For EDF the technical risks are high and consequently very appropriate R and D actions are required. In this context the Direction des Etudes et Recherches (DER) has developed a methodology for analysing concrete structure behaviour modelling. This approach has several aims: - making a distinction between the problems which refer to the existing models and those which require R and D; - displaying disciplinary links between different problems encountered on EDF structures (non-linear mechanical, chemical - hydraulic - mechanical coupling, etc); - listing of the existing tools and positioning the DER `Aster` finite element code among them. This document is a state of the art of scientific knowledge intended to shed light on the fields in which one should be involved when there is, on one part a strong requirement on the side of structure operators, and on the other one, the present tools do not allow this requirement to be satisfactorily met. The analysis has been done on 12 scientific subjects: 1) Hydration of concrete at early ages: exothermicity, hardening, autogenous shrinkage; 2) Drying and drying shrinkage; 3) Alkali-silica reaction and bulky stage formation; 4) Long term deterioration by leaching; 5) Ionic diffusion and associated attacks: the chlorides case; 6) Permeability / tightness of concrete; 7) Concretes -nonlinear behaviour and cracking (I): contribution of the plasticity models; 8) Concretes - nonlinear behaviour and cracking (II): contribution of the damage models; 9) Concretes - nonlinear behaviour and cracking (III): the contribution of the probabilistic analysis model; 10) Delayed behaviour of

    2014-10-01

    The knowledge of the infrared emissivity of materials used in buildings and civil engineering structures is useful for two specific approaches. First, quantitative diagnosis of buildings or civil engineering infrastructures by infrared thermography requires emissivity values in the spectral bandwidth of the camera used for measurements, in order to obtain accurate surface temperatures; for instance, emissivity in the band III domain is required when using cameras with uncooled detectors (such as micro-bolometer arrays). Second, setting up accurate thermal balances by numerical modeling requires the total emissivity value for a large wavelength domain; this is, for instance, the case for computing the road surface temperature to predict ice occurrence. Furthermore, periodical surveys of emissivity variations due to aging or soiling of surfaces could be useful in many situations such as thermal mapping of roads or building insulation diagnosis. The use of portable emissivity measurement devices is required for that purpose. A device using an indirect measurement method was previously developed in our lab; the method uses measurement of the reflectivity from a modulated IR source and requires calibration with a highly reflective surface. However, that device uses a low-frequency, thermal modulation well adapted to laboratory measurements but unfit for fast and in situ measurements. Therefore, a new, portable system which retains the principle of an indirect measurement but uses a faster-frequency, mechanical modulation more appropriate to outdoor measurements was developed. Both devices allow measurements in the broad m to m) and narrow m to m) bands. Experiments were performed on a large number of materials commonly used in buildings and civil engineering structures. The final objective of this work is to build a database of emissivity of these materials. A comparison of laboratory and on-site measurements of emissivity values obtained in both spectral bands will be

  7. Free vibration analysis of civil engineering structures by component-wise models

    Science.gov (United States)

    Carrera, Erasmo; Pagani, Alfonso

    2014-09-01

    Higher-order beam models are used in this paper to carry out free vibration analysis of civil engineering structures. Refined kinematic fields are developed using the Carrera Unified Formulation (CUF), which allows for the implementation of any-order theory without the need for ad hoc formulations. The principle of virtual displacements in conjunction with the finite element method (FEM) is used to formulate stiffness and mass matrices in terms of fundamental nuclei. The nuclei depend neither on the adopted class of beam theory nor on the FEM approximation along the beam axis. This paper focuses on a particular class of CUF models that makes use of Lagrange polynomials to discretize cross-sectional displacement variables. This class of models are referred to as component-wise (CW) in recent works. According to the CW approach, each structural component (e.g. columns, walls, frame members, and floors) can be modeled by means of the same 1D formulation. A number of typical civil engineering structures (e.g. simple beams, arches, truss structures, and complete industrial and civil buildings) are analyzed and CW results are compared to classical beam theories (Euler-Bernoulli and Timoshenko), refined beam models based on Taylor-like expansions of the displacements on the cross-section, and classical solid/shell FEM solutions from the commercial code MSC Nastran. The results highlight the enhanced capabilities of the proposed formulation. It is in fact demonstrated that CW models are able to replicate 3D solid results with very low computational efforts.

  8. Utilization of electromigration in civil and environmental engineering--processes, transport rates and matrix changes.

    Ottosen, Lisbeth M; Christensen, Iben V; Rorig-Dalgård, Inge; Jensen, Pernille E; Hansen, Henrik K

    2008-07-01

    Electromigration (movement of ions in an applied electric field) is utilized for supply or extraction of ions from various porous materials within both civil and environmental engineering. In civil engineering, most research has been conducted on the removal of chlorides from concrete to hinder reinforcement corrosion while in environmental engineering remediation of heavy metal polluted soil is the issue most studied. Never the less, experiments have been conducted with utilization for several other materials and purposes within both engineering fields. Even though there are many topics of common interest in the use of electromigration for the two fields, there is no tradition for collaboration. The present paper is a review with the aim of pointing out areas of shared interest. Focus is laid on the purposes of the different processes, transport rates of various ions in different materials and on changes in the matrix itself. Desorption and dissolution of the target elements into ionic form is a key issue to most of the processes, and can be the limiting step. The removal rate is generally below 1 cm day(- 1), but it can be much less than 1 mm day(- 1) when desorption is slow and insufficient. Matrix changes occurs under the action of the applied electric field and it includes both physico-chemical and hydrological changes. Some of the solid phases is weathered and new can be formed. Increased fundamental understanding of the effects and side effects, when applying the electric field to a porous material, can lead to improvement of the known technologies and possibly to new applications.

    Full Text Available The application of structural health monitoring (SHM systems to civil engineering structures has been a developing studied and practiced topic, that has allowed for a better understanding of structures’ conditions and increasingly lead to a more cost-effective management of those infrastructures. In this field, the use of fiber optic sensors has been studied, discussed and practiced with encouraging results. The possibility of understanding and monitor the distributed behavior of extensive stretches of critical structures it’s an enormous advantage that distributed fiber optic sensing provides to SHM systems. In the past decade, several R & D studies have been performed with the goal of improving the knowledge and developing new techniques associated with the application of distributed optical fiber sensors (DOFS in order to widen the range of applications of these sensors and also to obtain more correct and reliable data. This paper presents, after a brief introduction to the theoretical background of DOFS, the latest developments related with the improvement of these products by presenting a wide range of laboratory experiments as well as an extended review of their diverse applications in civil engineering structures.

    In this paper, we report on the vibration and displacement monitoring of civil engineering structures using a state of the art image assisted total station (IATS) and passive target markings. By utilizing the telescope camera of the total station, it is possible to capture video streams in real time with 10fps and an angular resolution of approximately 2″/px. Due to the high angular resolution resulting from the 30x optical magnification of the telescope, large distances to the object to be monitored are possible. The laser distance measurement unit integrated in the total station allows to precisely set the camera's focus position and to relate the angular quantities gained from image processing to units of length. To accurately measure the vibrations and displacements of civil engineering structures, we use circular target markings rigidly attached to the object. The computation of the targets' centers is performed by a least squares adjustment of an ellipse according to the Gauß-Helmert model from which the parameters of the ellipse and their standard deviations are derived. In laboratory experiments, we show that movements can be detected with an accuracy of better than 0.2mm for single frames and distances up to 30m. For static applications, where many video frames can be averaged, accuracies of better than 0.05mm are possible. In a field test on a life-size footbridge, we compare the vibrations measured by the IATS to reference values derived from accelerometer measurements.

    The application of structural health monitoring (SHM) systems to civil engineering structures has been a developing studied and practiced topic, that has allowed for a better understanding of structures' conditions and increasingly lead to a more cost-effective management of those infrastructures. In this field, the use of fiber optic sensors has been studied, discussed and practiced with encouraging results. The possibility of understanding and monitor the distributed behavior of extensive stretches of critical structures it's an enormous advantage that distributed fiber optic sensing provides to SHM systems. In the past decade, several R & D studies have been performed with the goal of improving the knowledge and developing new techniques associated with the application of distributed optical fiber sensors (DOFS) in order to widen the range of applications of these sensors and also to obtain more correct and reliable data. This paper presents, after a brief introduction to the theoretical background of DOFS, the latest developments related with the improvement of these products by presenting a wide range of laboratory experiments as well as an extended review of their diverse applications in civil engineering structures.

    We report on civil engineering applications of a fiber optic distributed strain sensor. It consists of a sensing fiber and a high performance optical time domain reflectometer (OTDR), for measuring both strain and optical loss distribution along optical fibers by accessing only one end of the fiber. The OTDR can measure distributed strain with an accuracy of better than +/- 60 X 10-6 and a high spatial resolution of up to 1 m over a 10 km long fiber. In model experiments using the OTDR, we measured the strain changes in fibers attached to the surface of a concrete test beam. The performance of the fiber strain sensor was tested by measuring the strain distribution in optical fibers and comparing the results with resistance strain gage measurements for several loads. We found that the two sets of results were similar, and in addition, we demonstrated experimentally that the sensor was able to measure an induced strain change of less than 100 by 10-6, which is nearly the elastic limit of the concrete material. These results show the potential of the OTDR to extend the application of monitoring systems to such areas as large building diagnostics for civil engineering.

    CERN is first and foremost a place where physicists study particle collisions. But to be able to observe the infinitely small, they need huge pieces of equipment, the accelerators and detectors, whose construction, some 100 metres below the earth's surface calls on the services of other fascinating disciplines. Take civil engineering, for example. For the construction of the LHC some 420 000 cubic metres of rock have had to be excavated for the 6500 metres of tunnel, 6 new shafts and 32 underground chambers and caverns. To avoid disrupting other experiments in progress, the work on these exceptional structures has had to be done without creating vibrations. The ATLAS experiment hall, a huge cathedral-like structure 100 metres below ground, is another mind-blowing feat of civil engineering. Its construction involved the use of ground-breaking technology, such as the system for suspending the ceiling put in place during the excavation work. At the next Discovery Monday, the specialists responsible for...

    For large civil engineering structures and base establishments, for example, bridges, super-high buildings, long-span space structures, offshore platforms and pipe systems of water & gas supply, their lives are up to a few decades or centuries. Damaged by environmental loads, fatigue effects, corrosion effects and material aging, these structures experience inevitably such side effects as damage accumulation, resistance reduction and even accidents. The traditional civil structure is a kind of passive one, whose performance and status are unpredictable to a great extent, but the informatics' introduction breaks a new path to obtain the status of the structure, thus it is an important research direction to evaluate and improve reliability of civil structures by the use of monitoring and health diagnosis technique, and this also assures the security of service for civil engineering structures. Smart material structure, originated from the aerospace sector, has been a research hotspot in civil engineering, medicine, shipping, and so on. For structural health monitoring of civil engineering, the research about high-performance sensing unit of smart material structure is very important, and this will possibly push further the development and application of monitoring and health diagnosis techniques. At present, piezoelectric materials are one of the most widely used sensing materials among the research of smart material structures. As one of the piezoelectric materials, PVDF(Polyvinylidene Fluoride)film is widely considered for the advantages of low cost, good mechanical ability, high sensibility, the ability of being easily placed and resistance of corrosion. However, only a few studies exit about building a mature monitoring system using PVDF. In this paper, for the sake of using PVDF for sensing unit for structural local monitoring of civil engineering, the strain sensing properties of PVDF are studied in detail. Firstly, the operating mechanism of PVDF is analyzed

    Goh, Yang Miang; Chua, Sijie

    2016-08-01

    Design for safety (DfS) (also known as prevention through design, safe design and Construction (Design and Management)) promotes early consideration of safety and health hazards during the design phase of a construction project. With early intervention, hazards can be more effectively eliminated or controlled leading to safer worksites and construction processes. DfS is practiced in many countries, including Australia, the UK, and Singapore. In Singapore, the Manpower Ministry enacted the DfS Regulations in July 2015, which will be enforced from August 2016 onwards. Due to the critical role of civil and structural (C&S) engineers during design and construction, the DfS knowledge, attitude and practices (KAP) of C&S engineers have significant impact on the successful implementation of DfS. Thus, this study aims to explore the DfS KAP of C&S engineers so as to guide further research in measuring and improving DfS KAP of designers. During the study, it was found that there is a lack of KAP studies in construction management. Therefore, this study also aims to provide useful lessons for future applications of the KAP framework in construction management research. A questionnaire was developed to assess the DfS KAP of C&S engineers. The responses provided by 43 C&S engineers were analyzed. In addition, interviews with experienced construction professionals were carried out to further understand perceptions of DfS and related issues. The results suggest that C&S engineers are supportive of DfS, but the level of DfS knowledge and practices need to be improved. More DfS guidelines and training should be made available to the engineers. To ensure that DfS can be implemented successfully, there is a need to study the contractual arrangements between clients and designers and the effectiveness of different implementation approaches for the DfS process. The questionnaire and findings in this study provided the foundation for a baseline survey with larger sample size, which is

    The use of high-temperature materials is especially important in power station construction,heating systems engineering, furnace industry, chemical and petrochemical industry, waste incineration plants, coal gasification plants and for flying gas turbines in civil and military aircrafts and helicopters. Particularly in recent years, the development of new processes and the drive to improve the economics of existing processes have increased the requirements significantly so that it is necessary to change from well-proven materials to new alloys. Hitherto, heat resistant ferritic steels sufficed in conventional power station constructions for temperatures up to 550℃ newly developed ferritic/martensitic steels provide sufficient strength up to about 600-620℃. In new processes, e.g. fiuidized-bed combustion of coal, process temperatures up to 900℃ occur. However, this is not the upper limit, since in combustion engines, e.g. gas turbines. Material temperatures up to 1100℃ are reached locally. Similar development trends can also be identified in the petrochemical industry and in the heat treatment and furnace engineering. The advance to ever higher material temperatures now not only has the consequence of having to use materials with enhanced high-strength properties, considerable attention now also has to be given to their chemical stability in corrosive media. Therefore not only examples of the use of high-temperature alloys for practical applications will be given but also be contributed to some general rules for material selection with regard to their high-temperature strength and corrosion resistance.

    The civil-engineering work for the construction of the Linac 4 accelerator has started on 22 October on the Mont Citron, the mound just opposite Restaurant No. 2 between the Computer Centre and the PS complex. Initially the work will involve excavating the mound and transporting the spoil to the area in front of Building SM18. This first phase of work will last for about five months until April 2009. The large number of lorries will cause disruption to traffic on the Route Rutherford, part of the Route Einstein and in the transfer tunnel between the two sites. Traffic lights for alternating traffic will be in operation at each end of the tunnel since there is insufficient room for two lorries travelling in opposite directions to use it at the same time. Consequently, users are strongly recommended not to use the tunnel except for transporting equipment between the two sites. Users not transporting equipment are strongly recommended ...

    The age of the civil engineering structure (office buildings, halls) and of tertiary technical equipment (mainly HVAC and electricity) at CERN is such that their renovation must be considered in the near future. Due to the large number of buildings and equipment in these conditions, and the restricted budget available, it is extremely important to define priorities. The aim of this note is to give the picture of the current conditions and the related problems, based on the backlog of CERN database (MP5) and confronting it with the inventory made at CERN by an external company. After having identified the most frequent problems and repairs to carry out, a planning for intervention is therefore presented optimizing the safety aspects, maintenance costs and comfort for the users. The timescale of this intervention is related to the money that will be available in the coming years.

  20. System identification of civil engineering structures with multiple inputs by decoupling output signals

    2014-03-01

    System identification of civil engineering structures are often formulated as Multiple-Input, Multiple-Output (MIMO) problems due to the complexity of loading conditions such as differential ground motion, which is also multi-directional in nature. Such MIMO system identification problems are challenging due to strong coupling between the contributions of multiple ground motion inputs to each individual response. Compared with Single-Input, Multiple-Output (SIMO) system identification, MIMO problems are often more computationally complex and error prone. In this paper, a new system identification strategy is proposed in which a more complex MIMO problem is converted into a number of SIMO problems by decoupling the contribution of multiple inputs to the outputs. A QR-factorization based approach is adopted for the decoupling and its accuracy is investigated. The effectiveness of the proposed strategy is demonstrated through applications to a two-span straight bridge and a four-span curved bridge, both are highway bridges.

    1998-01-01

    In April 1996, CERN awarded three contracts for civil engineering design services associated with the LHC project. The three contracts were awarded to three different joint ventures of firms from five member states. The total bid price for these services was in excess of 35 MCHF and the contracts will run for up to seven years. This paper aims to discuss and analyze the experience gained to date in the management of these contracts. In particular, the paper will address the issues of conditions of contract and specification for this form of contract. Current experience with each of the three consultants will be presented with the areas of difficulty highlighted. Conclusions will be made regarding future use of such contracts and in particular the way in which CERN must change in order to work efficiently with external designers.

This work consists of preparing didactic material (educational software aimed at tea- ching fluid mechanics, particularly analysing tube, tank and pumping systems, initially aimed at civil engineering students from the Universidad Santo Tomás in Bogotá. Such materials have been successfully developed and used in their formal programmes by several universities around the world during the last few years. The didactic software mentioned in this work was constructed using Visual Basic programming language. This has resulted in a very useful educational tool, leading to effective teacher—student communication which is suitable for both the classroom and students’ personal work (Angel y Bautista, 2001; Aguiar, 2002.

    Full Text Available For reliability testing an Energy Expansion Tree (EET and a companion Energy Function Model (EFM are proposed and described in this paper. Different from conventional approaches, the EET provides a more comprehensive and objective way to systematically identify external energy factors affecting reliability. The EFM introduces energy loss into a traditional Function Model to identify internal energy sources affecting reliability. The combination creates a sound way to enumerate the energies to which a system may be exposed during its lifetime. We input these energies into planning an accelerated life test, a Multi Environment Over Stress Test. The test objective is to discover weak links and interactions among the system and the energies to which it is exposed, and design them out. As an example, the methods are applied to the pipe in subsea pipeline. However, they can be widely used in other civil engineering industries as well. The proposed method is compared with current methods.

    The Boeing Company is investigating the feasibility of building a second generation supersonic transport. If current studies support its viability, this airplane, known as the High Speed Civil Transport (HSCT), could be launched early in the next century. The HSCT will cruise at Mach 2.4, be over 300 feet long, have an initial range of between 5000 and 6000 NM, and carry approximately 300 passengers. We are presently involved in developing an advanced flight deck for the HSCT. As part of this effort we are undertaking a human engineering analysis that involves a top-down, mission driven approach that will allow a systematic determination of flight deck functional and information requirements.

    2014-01-01

    Full Text Available The aim of this paper is to apply both time- and frequency-domain-based approaches on real-life civil engineering structures and to assess their capability for damage detection. The methodology is based on Principal Component Analysis of the Hankel matrix built from output-only measurements and of Frequency Response Functions. Damage detection is performed using the concept of subspace angles between a current (possibly damaged state and a reference (undamaged state. The first structure is the Champangshiehl Bridge located in Luxembourg. Several damage levels were intentionally created by cutting a growing number of prestressed tendons and vibration data were acquired by the University of Luxembourg for each damaged state. The second example consists in reinforced and prestressed concrete panels. Successive damages were introduced in the panels by loading heavy weights and by cutting steel wires. The illustrations show different consequences in damage identification by the considered techniques.

    2013-04-01

    Ground Penetrating Radar (GPR) is a safe, non-destructive and non-invasive imaging technique that can be effectively used for advanced inspection of composite structures and for diagnostics affecting the whole life-cycle of civil engineering works. GPR provides high resolution images of structures and subsurface through wide-band electromagnetic waves. It can be employed for the surveying of roads, pavements, bridges, tunnels, for detecting underground cavities and voids, for utility sensing, for the inspection of buildings, reinforced concrete and pre-cast concrete structures, for geotechnical investigation, in foundation design, as well as for several other purposes. Penetration and resolution of GPR depend primarily on the transmitting frequency of the equipment, the antenna characteristics, the electrical properties of the ground or of the surveyed material, and the contrasting electrical properties of the targets with respect to the surrounding medium. Generally there is a direct relationship between the transmitter frequency and the resolution that can be obtained; conversely there is an inverse relationship between frequency and penetration depth. GPR works best in dry ground environments, but can also give good results in wet, saturated materials; it does not work well in saline conditions, in high-conductivity media and through dense clays which limit signal penetration. Different approaches can be employed in the processing of collected GPR data. Once data have been processed, they still have to be analysed. This is a challenging problem, since interpretation of GPR radargrams is typically non-intuitive and considerable expertise is needed. In the presence of a complex scenario, an accurate electromagnetic forward solver is a fundamental tool for the validation of data interpretation. It can be employed for the characterization of scenarios, as a preliminary step that precedes a survey, or to gain a posteriori a better understanding of measured data. It

    Mathematics and engineering are inexorably and significantly linked and essentially required in analyzing and accessing thought to make good judgment when dealing in complex and varied engineering problems. A study in the current engineering education curriculum to explore how the critical thinking and mathematical thinking relates to one another, is therefore timely crucial. Unfortunately, there is not much information available explicating about the link. This paper aims to report findings of a critical review as well as to provide brief description of an on-going research aimed to investigate the dispositions of critical thinking and the relationship and integration between critical thinking and mathematical thinking during the execution of civil engineering tasks. The first part of the paper reports an in-depth review on these matters based on rather limited resources. The review showed a considerable form of congruency between these two perspectives of thinking, with some prevalent trends of engineering workplace tasks, problems and challenges. The second part describes an on-going research to be conducted by the researcher to investigate rigorously the relationship and integration between these two types of thinking within the perspective of civil engineering tasks. A reasonably close non-participant observations and semi-structured interviews will be executed for the pilot and main stages of the study. The data will be analyzed using constant comparative analysis in which the grounded theory methodology will be adopted. The findings will serve as a useful grounding for constructing a substantive theory revealing the integral relationship between critical thinking and mathematical thinking in the real civil engineering practice context. The substantive theory, from an angle of view, is expected to contribute some additional useful information to the engineering program outcomes and engineering education instructions, aligns with the expectations of

    Full Text Available Scientific and professional interests of civil engineering mainly include structures, hydraulics, geotechnical engineering, environment, and transportation issues. Topics included in the context of the above may concern urban environment issues, urban planning, hydrological modelling, study of hazards and road construction. Land cover information contributes significantly on the study of the above subjects. Land cover information can be acquired effectively by visual image interpretation of satellite imagery or after applying enhancement routines and also by imagery classification. The Landsat Data Continuity Mission (LDCM – Landsat 8 is the latest satellite in Landsat series, launched in February 2013. Landsat 8 medium spatial resolution multispectral imagery presents particular interest in extracting land cover, because of the fine spectral resolution, the radiometric quantization of 12bits, the capability of merging the high resolution panchromatic band of 15 meters with multispectral imagery of 30 meters as well as the policy of free data. In this paper, Landsat 8 multispectral and panchromatic imageries are being used, concerning surroundings of a lake in north-western Greece. Land cover information is extracted, using suitable digital image processing software. The rich spectral context of the multispectral image is combined with the high spatial resolution of the panchromatic image, applying image fusion – pansharpening, facilitating in this way visual image interpretation to delineate land cover. Further processing concerns supervised image classification. The classification of pansharpened image preceded multispectral image classification. Corresponding comparative considerations are also presented.

    Full Text Available The civil and environmental engineering disciplines have identified the levels of knowledge about sustainability that are desirable for students to achieve as they graduate with a bachelor’s degree, as well as sustainability-related competencies to be obtained during a master’s degree, and on-the-job, prior to professional licensure. Different pedagogies are better suited to help students attain these levels of cognitive ability, while also developing affective outcomes. This paper provides examples of different methods that have been used at one institution to educate engineering students about sustainability, supported with data that indicates whether the method successfully achieved the targeted learning outcomes. Lectures, in-class active learning, readings, and appropriately targeted homework assignments can achieve basic sustainability knowledge and comprehension by requiring students to define, identify, and explain aspects of sustainability. Case studies and the application of software tools are good methods to achieve application and analysis competencies. Project-based learning (PBL and project-based service-learning (PBSL design projects can reach the synthesis level and may also develop affective outcomes related to sustainability. The results provide examples that may apply to a wider range of disciplines and suggest sustainability outcomes that are particularly difficult to teach and/or assess.

Some example, where it has been used in roadbase and subbase of gravel roads, are in the counties of Uppsala, Soedermanland, Vaestmanland and in Finland. The use of fly ash has contributed to good function for example as bearing capacity, thaw and frost capacity and good durability. This has also reduced costs for maintenance. The objective of this project was to develop a manual to provide a base for contemporary use of fly ash in road constructions. In the manual experience from studies, field tests and regulations has been compiled. The manual handles fly ash as base for products to be used in base and subbase in gravel roads. Future user of the guidelines are mainly consultant engineers and contractors. However the aim of the manual is to also support road administrators, environmental authorities and industry. The project has been carried out parallel to another ongoing national project titled 'Guidelines, Use of alternative materials in civil engineering'. The objective of that project is to establish a base for handling of alternative materials in Sweden. Fly ash in gravel roads are mainly used in two typical applications, one without any additive in a single layer and one with fly ash mixed with gravel. The use of flyash provides functional properties such as increased stiffness, stability and enhanced frost and thaw capacity for the road construction in total. Furthermore the products based on fly ash will have low permeability and good frost and thaw durability. These properties are for example related to fly ash quality, design and construction and are in general expected to be better than for traditional constructions using, for example, sand or gravel. The properties can be enhanced further by using binders such as cement and Merit. Fly ash should always be used above the ground water table with

    This paper focuses on the conceptual design of a two spool compressor for the NASA Large Civil Tilt Rotor engine, which has a design-point pressure ratio goal of 30:1 and an inlet weight flow of 30.0 lbm/sec. The compressor notional design requirements of pressure ratio and low-pressure compressor (LPC) and high pressure ratio compressor (HPC) work split were based on a previous engine system study to meet the mission requirements of the NASA Subsonic Rotary Wing Projects Large Civil Tilt Rotor vehicle concept. Three mean line compressor design and flow analysis codes were utilized for the conceptual design of a two-spool compressor configuration. This study assesses the technical challenges of design for various compressor configuration options to meet the given engine cycle results. In the process of sizing, the technical challenges of the compressor became apparent as the aerodynamics were taken into consideration. Mechanical constraints were considered in the study such as maximum rotor tip speeds and conceptual sizing of rotor disks and shafts. The rotor clearance-to-span ratio in the last stage of the LPC is 1.5% and in the last stage of the HPC is 2.8%. Four different configurations to meet the HPC requirements were studied, ranging from a single stage centrifugal, two axi-centrifugals, and all axial stages. Challenges of the HPC design include the high temperature (1,560deg R) at the exit which could limit the maximum allowable peripheral tip speed for centrifugals, and is dependent on material selection. The mean line design also resulted in the definition of the flow path geometry of the axial and centrifugal compressor stages, rotor and stator vane angles, velocity components, and flow conditions at the leading and trailing edges of each blade row at the hub, mean and tip. A mean line compressor analysis code was used to estimate the compressor performance maps at off-design speeds and to determine the required variable geometry reset schedules of the

    Full Text Available This contribution is dedicated to demonstrating the high potential and manifold applications of state-of-the-art computational fluid dynamics (CFD tools for free-surface flows in civil and environmental engineering. All simulations were performed with the academic research code ELBE (efficient lattice boltzmann environment, http://www.tuhh.de/elbe. The ELBE code follows the supercomputing-on-the-desktop paradigm and is especially designed for local supercomputing, without tedious accesses to supercomputers. ELBE uses graphics processing units (GPU to accelerate the computations and can be used in a single GPU-equipped workstation of, e.g., a design engineer. The code has been successfully validated in very different fields, mostly related to naval architecture and mechanical engineering. In this contribution, we give an overview of past and present applications with practical relevance for civil engineers. The presented applications are grouped into three major categories: (i tsunami simulations, considering wave propagation, wave runup, inundation and debris flows; (ii dam break simulations; and (iii numerical wave tanks for the calculation of hydrodynamic loads on fixed and moving bodies. This broad range of applications in combination with accurate numerical results and very competitive times to solution demonstrates that modern CFD tools in general, and the ELBE code in particular, can be a helpful design tool for civil and environmental engineers.

    Highlights: ► A seismic load can be of any type from force-controlled to displacement-controlled. ► Seismic input and structural features play a concurrent role in seismic load categorization. ► A margin index is introduced, which controls seismic load categorization. ► A formula is given for calculating the margin index. ► A formula is given that provides the primary part of a seismically-induced stress. -- Abstract: Both civil and mechanical engineers come across loads of the force-controlled type (qualified as “primary”) or of the displacement-controlled type (qualified as “secondary”). For decades, different authors with either civil or mechanical backgrounds have been debating whether a particular seismic load should be classified as primary or secondary, but without apparent mutual understanding or mutual benefit so far. The purpose of this paper is to bring some clarity to the subject by considering a family of oscillators, which are characterized by their ductile capacity, μ{sub u}, and their “effective stiffness factor”, τ. The considered range of τ values (0 < τ < 1) enables to cover all cases from the perfect damage to the perfect non-damage models. A structural index λ is also introduced, which is a mix of ductility and effective stiffness factor. It is concluded that a seismic input cannot be a priori regarded as primary or secondary. Both the λ value of the structure or component and the slope, p, of the input spectrum in the vicinity of its (dominant) natural frequency should be considered concurrently when making a decision about stress categorization. A margin index m is introduced, which controls seismic load/stress categorization. A formula is given that provides the primary part of a seismically-induced stress.

  3. Curricular Reform: Systems Modeling and Sustainability in Civil and Environmental Engineering at the University of Vermont

    Researchers at the University of Vermont were awarded a NSF-sponsored Department Level Reform (DLR) grant to incorporate a systems approach to engineering problem solving within the civil and environmental engineering programs. A systems approach challenges students to consider the environmental, social, and economic aspects within engineering solutions. Likewise, sustainability requires a holistic approach to problem solving that includes economic, social and environmental factors. Our reform has taken a multi-pronged approach in two main areas that include implementing: a) a sequence of three systems courses related to environmental and transportation systems that introduce systems thinking, sustainability, and systems analysis and modeling; and b) service-learning (SL) projects as a means of practicing the systems approach. Our SL projects are good examples of inquiry-based learning that allow students to emphasize research and learning in areas of most interest to them. The SL projects address real-world open-ended problems. Activities that enhance IT and soft skills for students are incorporated throughout the curricula. Likewise, sustainability has been a central piece of the reform. We present examples of sustainability in the SL and modeling projects within the systems courses (e.g., students have used STELLA™ systems modeling software to address the impact of different carbon sequestration strategies on global climate change). Sustainability in SL projects include mentoring home schooled children in biomimicry projects, developing ECHO exhibits and the design of green roofs, bioretention ponds and porous pavement solutions. Assessment includes formative and summative methods involving student surveys and focus groups, faculty interviews and observations, and evaluation of student work.

  4. Rhetorical Impact through Hedging Devices in the ‘Results and Discussion’ Part of a Civil Engineering Research Article

    Full Text Available It is common knowledge that hedging devices as a rhetorical technique common in all persuasive writing are considerably important in scientific discourse, for they are tools which facilitate presenting claims or arguments in a polite, acceptable and respectful manner. In addition, they are discoursal resources available to a scientific writer’s propositions to express uncertainty, skepticism, and open-mindedness. Research articles are an important means of communication between different members of a discourse community, and will be convincing to a certain extent only when authors are able to employ rhetorical conventions, such as hedging devices, persuasively. However, hedging is a problematic aspect in EAP learning since rarely are the learners able to hedge their statements appropriately, engineering students not being an exception. Therefore, this article tends to linguistically analyze the function of rhetorical impact of using hedging devices in the results and discussion part of a civil engineering research article published in the Asian Journal of Civil Engineering (Building & Housing to conclude that a greater and more systematic attention should be given to hedging devices considering their importance in EAP. The implication is that students, especially the Non Native English Speakers, be taught how to recognize and effectively use hedging devices in their writing as they do not seem to be familiar with hedges and therefore find it particularly difficult to hedge their statements appropriately.

    Aging of transport infrastructures combined with traffic and climatic solicitations contribute to the reduction of their performances. To address and quantify the resilience of civil engineering structure, investigations on robust, fast and efficient methods are required. Among research works carried out at IFSTTAR, methods for long term monitoring face an increasing demand. Such works take benefits of this last decade technological progresses in ICT domain. The present study follows the ISTIMES European project [1], which aimed at demonstrate the ability of different electromagnetic sensing techniques, processing methods and ICT architecture, to be used for long term monitoring of critical transport infrastructures. Thanks to this project a multi-sensing techniques system, able to date and synchronize measurements carried out by infrared thermography coupled with various measurements data (i.e. weather parameters), have been designed, developed and implemented on real site [2]. Among experiments carried out on real transport infrastructure, it has been shown, for the "Musmesci" bridge deck (Italy), that by using infrared thermal image sequence with weather measurements during sevral days it was possible to develop analysis methods able to produce qualitative and quantitative data [3]. In the present study, added functionalities were designed and added to the "IrLAW" system in order to reach full autonomy in term of power supply, very long term measurement capability (at least 1 year) and automated data base feeding. The surveyed civil engineering structures consist in two concrete beams of 16 m long and 21 T weight each. One of the two beams was damage by high energy mechanical impact at the IFSTTAR falling rocks test station facilities located in the French Alpes [4]. The system is composed of one IR uncooled microbolometric camera (FLIR SC325) with a 320X240 Focal Plane Array detector in band III, a weather station VAISALA WXT520, a GPS, a failover power supply

    Full Text Available This project work addresses the crucial need to encourage undergraduate civil and environmental engineering students to gain employment skills and training right from the start of their studies so that their overall employability increases; their confidence level in networking with industry and within the workplace increases; and so that they are successfully able to obtain employment after finishing their studies. This initiative is a stepping-stone employability exercise which focuses specifically on first year students to help them engage with industry right from the start of their course. It is proposed that they would gain some realistic work experience both individually and as part of group within a virtual work environment using an action learning approach. The virtual environment used was based on SecondLife, a popular virtual reality programme. A pilot scheme was set up and run at Brunel University during the summer of 2014 using eight self-selecting first year students. The scheme’s outputs were extensively monitored and evaluated to assess its impact on the development of employability skills. This approach may prove a cost effective way of letting students gain an insight into the workplace whilst improving these skills. It may also prove a way for employers to select from a large range of students the best to actually undertake their real work-based internships.

    2008-01-01

    The civil-engineering work for the construction of the Linac 4 accelerator will start on 22 October on the Mont Citron, the mound just opposite Restaurant No. 2 between the Computer Centre and the PS complex. Initially the work will involve excavating the mound and transporting the spoil to the area in front of Building SM18. This first phase of work will last for about five months until April 2009. The large number of lorries will cause disruption to traffic on the Route Rutherford, part of the Route Einstein and in the transfer tunnel between the two sites. Traffic lights for alternating traffic will be in operation at each end of the tunnel since there is insufficient room for two lorries travelling in opposite directions to use it at the same time. Consequently, users are strongly recommended not to use the tunnel except for transporting equipment between the two sites. Users not transporting equipment are strongly recommended to use Gates A and B. In parallel, a temporary roundabout will be installed ...

    Ehrhart, Matthias; Lienhart, Werner

    2015-04-01

    Today, many large-scale civil engineering structures are permanently monitored to provide early warnings and to initiate counter actions from structural failure. Total station measurements are commonly used to determine 3D movements of selected points with measurement intervals of several minutes or hours. However, these measurements do not provide information on the vibration behavior of the structures. For this purpose, other sensors like accelerometers have to be installed on the object. In this paper, we present a monitoring system based on a state of the art image assisted total station (IATS) suitable for the measurement of absolute 3D coordinates and the determination of the structure's natural frequencies. The 3D coordinates can be determined with an accuracy of a few millimeters using conventional total station measurements. For analyzing the structure's natural frequencies, the telescope camera of the IATS is used in combination with dedicated image processing techniques optimized for artificial and natural targets. While the determination of 3D coordinates based on total station measurements is common practice, the idea of using the total station's image data for frequency analysis is new. Consequently, investigations on the achievable performance are pending for commercially available products. We therefore evaluate the potential of this technique at a life-size footbridge by comparison with accelerometer measurements. We demonstrate that with our developed monitoring concept and state of the art hardware, accelerometer measurements can be replaced in several monitoring situations by IATS measurements and image processing techniques.

    Full Text Available Environmental and sustainability assessment tools have an important role in moving towards a better world, bringing knowledge and raising awareness. In the architecture and civil engineering sector, these assessment tools help in moving forward to constructions that have less economic, environmental and social impacts. At present, there are numerous assessment tools and methods with different approaches and scopes that have been analyzed in numerous technical reviews. However, there is no agreement about which method should be used for each evaluation case. This research paper synthetically analyzes the main sustainability assessment methods for the construction sector, comparing their strengths and weaknesses in order to present the challenges of the Spanish Integrated Value Model for Sustainability Assessment (MIVES. MIVES is a Multi-Criteria Decision Making method based on the value function concept and the Seminars of experts. Then, this article analyzes MIVES advantages and weak points by going through its methodology and two representative applications. At the end, the area of application of MIVES is described in detail along with the general application cases of the main types of assessment tools and methods.

    This study is aimed for investigation of fly ash binder with suitable properties for civil engineering needs. The fly ash from Czech brown coal power plant Prunerov II was used and mechanically activated to achieve suitable particle size for alkaline activation of hardening process. This process is driven by dissolution of aluminosilicate content of fly ash and by subsequent development of inorganic polymeric network called geopolymer. Hardening kinetics at 25 and 30 °C were measured by strain controlled small amplitude oscillatory rheometry with strain of 0.01 % and microstructure of hardened binder was evaluated by scanning electron microscopy. Strength development of hardened binder was investigated according to compressional and flexural strength for a period of 180 days. Our investigation finds out, that mechanically activated fly ash can be comparable to metakaolin geopolymers, according to setting time and mechanical parameters even at room temperature curing. Moreover, on the bases of long time strength development, achieved compressional strength of 134.5 after 180 days is comparable to performance of high grade Portland cement concretes.

  11. Advanced spatio-temporal filtering techniques for photogrammetric image sequence analysis in civil engineering material testing

    Liebold, F.; Maas, H.-G.

    2016-01-01

    The paper shows advanced spatial, temporal and spatio-temporal filtering techniques which may be used to reduce noise effects in photogrammetric image sequence analysis tasks and tools. As a practical example, the techniques are validated in a photogrammetric spatio-temporal crack detection and analysis tool applied in load tests in civil engineering material testing. The load test technique is based on monocular image sequences of a test object under varying load conditions. The first image of a sequence is defined as a reference image under zero load, wherein interest points are determined and connected in a triangular irregular network structure. For each epoch, these triangles are compared to the reference image triangles to search for deformations. The result of the feature point tracking and triangle comparison process is a spatio-temporally resolved strain value field, wherein cracks can be detected, located and measured via local discrepancies. The strains can be visualized as a color-coded map. In order to improve the measuring system and to reduce noise, the strain values of each triangle must be treated in a filtering process. The paper shows the results of various filter techniques in the spatial and in the temporal domain as well as spatio-temporal filtering techniques applied to these data. The best results were obtained by a bilateral filter in the spatial domain and by a spatio-temporal EOF (empirical orthogonal function) filtering technique.

  12. Optimising a modified free-space permittivity characterisation method for civil engineering applications

    Muller, Wayne; Scheuermann, Alexander

    2016-04-01

    Measuring the electrical permittivity of civil engineering materials is important for a range of ground penetrating radar (GPR) and pavement moisture measurement applications. Compacted unbound granular (UBG) pavement materials present a number of preparation and measurement challenges using conventional characterisation techniques. As an alternative to these methods, a modified free-space (MFS) characterisation approach has previously been investigated. This paper describes recent work to optimise and validate the MFS technique. The research included finite difference time domain (FDTD) modelling to better understand the nature of wave propagation within material samples and the test apparatus. This research led to improvements in the test approach and optimisation of sample sizes. The influence of antenna spacing and sample thickness on the permittivity results was investigated by a series of experiments separating antennas and measuring samples of nylon and water. Permittivity measurements of samples of nylon and water approximately 100 mm and 170 mm thick were also compared, showing consistent results. These measurements also agreed well with surface probe measurements of the nylon sample and literature values for water. The results indicate permittivity estimates of acceptable accuracy can be obtained using the proposed approach, apparatus and sample sizes.

    2008-03-01

    Fiber reinforced polymer (FRP) materials are currently used for strengthening civil engineering infrastructures. The strengthening system is dependant on the bond characteristics of the FRP to the external surface of the structure to be effective in resisting the applied loads. This paper presents an innovative self-monitoring FRP strengthening system. The system consists of two components which can be embedded in FRP materials to monitor the global and local behavior of the strengthened structure respectively. The first component of the system is designed to evaluate the applied load acting on a structure based on elongation of the FRP layer along the entire span of the structure. Success of the global system has been demonstrated using a full-scale prestressed concrete bridge girder which was loaded up to failure. The test results indicate that this type of sensor can be used to accurately determine the load prior to failure within 15 percent of the measured value. The second sensor component consists of fiber Bragg grating sensors. The sensors were used to monitor the behavior of steel double-lap shear splices tested under tensile loading up to failure. The measurements were used to identify abnormal structural behavior such as epoxy cracking and FRP debonding. Test results were also compared to numerical values obtained from a three dimensional shear-lag model which was developed to predict the sensor response.

    The application of non-destructive testing and evaluation (NDT/NDE) methodologies in civil engineering has raised a growing interest during the last years because of its potential impact in several different scenarios. As a consequence, Ground Penetrating Radar (GPR) technologies have been widely adopted as an instrument for the inspection of the structural stability of buildings and for the detection of cracks and voids. In this framework, the development and validation of GPR algorithms and methodologies represents one of the most active research areas within the ELEDIA Research Center of the University of Trento. More in detail, great efforts have been devoted towards the development of inversion techniques based on the integration of deterministic and stochastic search algorithms with multi-focusing strategies. These approaches proved to be effective in mitigating the effects of both nonlinearity and ill-posedness of microwave imaging problems, which represent the well-known issues arising in GPR inverse scattering formulations. More in detail, a regularized multi-resolution approach based on the Inexact Newton Method (INM) has been recently applied to subsurface prospecting, showing a remarkable advantage over a single-resolution implementation [1]. Moreover, the use of multi-frequency or frequency-hopping strategies to exploit the information coming from GPR data collected in time domain and transformed into its frequency components has been proposed as well. In this framework, the effectiveness of the multi-resolution multi-frequency techniques has been proven on synthetic data generated with numerical models such as GprMax [2]. The application of inversion algorithms based on Bayesian Compressive Sampling (BCS) [3][4] to GPR is currently under investigation, as well, in order to exploit their capability to provide satisfactory reconstructions in presence of single and multiple sparse scatterers [3][4]. Furthermore, multi-scaling approaches exploiting level

    Many consulting assignments undertaken by Oxand within the framework of life-cycle management of existing nuclear civil engineering structures, relied on taking into account the structure's level of deterioration, the quantitative estimate of its residual strength capacity and the future progression of this capacity over time. The developments of structure assessment techniques allow more and more the integration of the real state of the existing structure by enhancing the value of measures and investigations carried out on structures. On one hand, this information allows to take into account the structure's ageing and therefore estimate the residual resistance and reliability. On the other hand, by investigating the real properties of the structure and of its operation, refined calculations can sometimes highlight a resistance margin of the structure 'such as built' higher than the one considered during design. The precision on the 'real' reliability of the structure allows to refine its management and thus to optimize the infrastructure's performance. Developments of assessment methods are increasingly oriented toward probabilistic approaches. Although they go out of the 'classical regulatory' framework, they bring precision on the 'real' reliability of the structure. Using higher assessment levels needs to have more important and precise input data, what can lead to the need to carry out more detailed investigations. However, these methods offer interesting ways, which can provide, in certain cases, useful additional information for the decision-making of actions to be engaged. The methodology is illustrated with the case of a network of reinforced concrete beams, which are subjected to a rapid increase in their mechanical stresses. In particular this example shows that investigations on the real performances of materials can provided a significant contribution in managing the risks of unavailability

    The engineering careers models were diverse in Europe, and are adopting now in Spain the Bolonia process for European Universities. Separated from older Universities, that are in part technically active, Civil Engineering (Caminos, Canales y Puertos) started at end of 18th century in Spain adopting the French models of Upper Schools for state civil servants with exam at entry. After 1800 intense wars, to conserve forest regions Ingenieros de Montes appeared as Upper School, and in 1855 also the Ingenieros Agrónomos to push up related techniques and practices. Other Engineers appeared as Upper Schools but more towards private factories. These ES got all adapted Lower Schools of Ingeniero Tecnico. Recently both grew much in number and evolved, linked also to recognized Professions. Spanish society, into European Community, evolved across year 2000, in part highly well, but with severe discordances, that caused severe youth unemployment with 2008-2011 crisis. With Bolonia process high formal changes step in from 2010-11, accepted with intense adaptation. The Lower Schools are changing towards the Upper Schools, and both that have shifted since 2010-11 various 4-years careers (Grado), some included into the precedent Professions, and diverse Masters. Acceptation of them to get students has started relatively well, and will evolve, and acceptation of new grades for employment in Spain, Europe or outside will be essential. Each Grado has now quite rigid curricula and programs, MOODLE was introduced to connect pupils, some specific uses of Personal Computers are taught in each subject. Escuela de Agronomos centre, reorganized with its old name in its precedent buildings at entrance of Campus Moncloa, offers Grados of Agronomic Engineering and Science for various public and private activities for agriculture, Alimentary Engineering for alimentary activities and control, Agro-Environmental Engineering more related to environment activities, and in part Biotechnology also

    The aim of this study was to use the Hiroshima University - Dental Behavioral Inventory (HU-DBI) to compare oral health attitudes and behavior of dental and civil engineering students in Colombia. The HU-DBI's survey consisting of twenty dichotomous responses (agree-disagree) regarding tooth brushing, was completed at University Antonio Narino for the dental students and the University of Cauca for the civil engineering students. The Spanish version of the HU-DBI questionnaire was taken by 182 of 247 dental students and 411 of 762 engineering students. The data was-statistically analyzed by the chi-square test and backward logistic regression. Compared to the engineering students, the dental students were more likely to agree with questions such as "I am bothered by the color of my gums"(OR = 2.2, 95% CI: 1.3-3.7),"I think I can clean my teeth well without using toothpaste" (OR = 3.0, 95% CI: 1.5-5.9), "I have used a dye to see how clean my teeth are" (OR = 2.9, 95% CI: 1.9-4.3), and "I have had my dentist tell me that I brush very well" (OR = 2.0, 95% CI: 1.3-3.1). The dental education curriculum in a dental school compared to a civil engineering school in Colombia indicated that a three-phase curriculum in didactics and clinics increased oral health attitudes and behavior from entry to graduation.

    2005-01-01

    Stress distribution of holed geotextile cross-section under uniaxial and double-axial tension is analyzed with the boundary element method (BEM). The calculation results indicate that stress distribution of holed geotextile crosssection is greatly related to the dimension of the specimen, the size of the hole, the shape of the hole and the tensile condition, and the stress concentration area of holed geotextile from the side of the hole to 3-4 times of the hole diameter should be strengthened in order to improve quality of the projects. These results could provide guidance for engineering application of geotextiles.

  3. Detecting steel rods and micro-piles: A case history in a civil engineering application

    Science.gov (United States)

    Orlando, Luciana

    2012-06-01

    Investigating engineered structures with GPR is challenging because quite often the scale of important features is similar or smaller that the natural scale of heterogeneity in the material. In this paper I summarize the key factors and use numerical simulations and real data examples to illustrate the tradeoff between detection and resolution. The targets were micro-piles and steel bars with diameters 0.13 m and 0.02 m, respectively, and embedded in an ancient wall that consists of an aggregate of stones ranging in size from 1 cm to half meter, mortar and air. The data were collected with center frequency antennas of 200, 600, 2000 MHz which provide increasing resolution. The model and measurement results indicate that lower resolution may result in a better understanding of the structure imaged with GPR. In fact, high resolution profiles show enhanced anomalies caused by heterogeneities in the host material, making data interpretation more difficult. This study shows that GPR survey design must be clear about the particular engineering objective and requires selecting the optimal frequency and bandwidth depending on the target dimension.

  4. STRATEGY FOR IMPROVEMENT OF SAFETY AND EFFICIENCY OF COMPUTER-AIDED DESIGN ANALYSIS OF CIVIL ENGINEERING STRUCTURES ON THE BASIS OF THE SYSTEM APPROACH

    Directory of Open Access Journals (Sweden)

    Zaikin Vladimir Genrikhovich

    2012-12-01

    Full Text Available The authors highlight three problems of the age of information technologies and proposes the strategy for their resolution in relation to the computer-aided design of civil engineering structures. The authors express their concerns in respect of globalization of software programmes designated for the analysis of civil engineering structures and employed outside of Russia. The problem of the poor quality of the input data has reached Russia. Lately, the rate of accidents of buildings and structures has been growing not only in Russia. Control over efficiency of design projects is hardly performed. This attitude should be changed. Development and introduction of CAD along with the application the efficient methods of projection of behaviour of building structures are in demand. Computer-aided calculations have the function of a logical nucleus, and they need proper control. The system approach to computer-aided calculations and technologies designated for the projection of accidents is formulated by the authors. Two tasks of the system approach and fundamentals of the strategy for its implementation are formulated. The study of cases of negative results of computer-aided design of engineering structures was performed and multi-component design patterns were developed. Conclusions concerning the results of researches aimed at regular and wide-scale implementation of the strategy fundamentals are formulated. Organizational and innovative actions concerning the projected behaviour of civil engineering structures proposed in the strategy are to facilitate: safety and reliability improvement of buildings and structures; saving of building materials and resources; improvement of labour efficiency of designers; modernization and improvement of accuracy of projected behaviour of buildings and building standards; closer ties between civil and building engineering researchers and construction companies; development of competitive environment to boost

  5. Experimental Investigation of the Effects of Reverse Bending and Straightening Process on Carbon Steel Bars used for Civil Engineering Applications

    Directory of Open Access Journals (Sweden)

    Adewole, K. K.

    2014-01-01

    Full Text Available This paper presents an experimental investigation of the effects of reverse bending and straightening process on the mechanical properties of a typical carbon steel bar used for civil engineering applications. Twenty four specimens each were used for the metallogarphy, microhardness and tensile tests. The investigation revealed that the reverse bending and straightening process has no significant effect on the bars’ through-thickness microstructure and hardness. However, the reverse bending and straightening process reduces the yield load, ultimate load, and displacement at fracture of the bars by 4.27%, 2.58%, and 18.62% respectively. These results highlight the need to take into consideration the effects of the previous loading history of the bars/wires, particularly the reduction in the displacement at fracture and consequently, the ductility of the bars/wires in the design and fitness for purpose assessment of components made from them, since the bars/wires could experience high strain during installation and in service due to overloads.

    2011-06-01

    Until recently, civil engineering material calibration data could only be obtained from material sample cores or via time consuming, stationary calibration measurements in a limited number of locations. Calibration data are used to determine material propagation velocities of electromagnetic waves in test materials for use in layer thickness measurements and subsurface imaging. Limitations these calibration methods impose have been a significant impediment to broader use of nondestructive evaluation methods such as ground-penetrating radar (GPR). In 2006, a new rapid, continuous calibration approach was designed using simulation software to address these measurement limitations during a Federal Highway Administration (FHWA) research and development effort. This continuous calibration method combines a digitally-synthesized step-frequency (SF)-GPR array and a data collection protocol sequence for the common midpoint (CMP) method. Modeling and laboratory test results for various data collection protocols and materials are presented in this paper. The continuous-CMP concept was finally implemented for FHWA in a prototype demonstration system called the Advanced Pavement Evaluation (APE) system in 2009. Data from the continuous-CMP protocol is processed using a semblance/coherency analysis to determine material propagation velocities. Continuously calibrated pavement thicknesses measured with the APE system in 2009 are presented. This method is efficient, accurate, and cost-effective.

    2015-01-01

    A moment tensor inversion (MTI) code originally developed to compute source mechanisms from mining-induced seismicity data is now being used in the laboratory in a civil engineering research environment. Quantitative seismology methods designed for geological environments are being tested with the aim of developing techniques to assess and monitor fracture processes in structural concrete members such as bridge girders. In this paper, we highlight aspects of the MTI_Toolbox programme that make it applicable to performing inversions on acoustic emission (AE) data recorded by networks of uniaxial sensors. The influence of the configuration of a seismic network on the conditioning of the least-squares system and subsequent moment tensor results for a real, 3-D network are compared to a hypothetical 2-D version of the same network. This comparative analysis is undertaken for different cases: for networks consisting entirely of triaxial or uniaxial sensors; for both P and S-waves, and for P-waves only. The aim is to guide the optimal design of sensor configurations where only uniaxial sensors can be installed. Finally, the findings of recent laboratory experiments where the MTI_Toolbox has been applied to a concrete beam test are presented and discussed.

    This article examines the application of knowledge creation learning and innovation to higher education in construction. The objectives are to demonstrate the application of the course based on knowledge creation learning to mass teaching and to analyse whether knowledge creation learning improves student motivation and learning. The empirical data (n = 120) consist of the results of a student survey from two university-level courses. The first course, Basics of Construction Management and Economics (n = 79), was developed on the basis of knowledge creation, and the second course, Building Project (n = 41), was implemented using the case-based learning method. The results, based on student self-assessments, showed that case-based learning supported the learning process more effectively than did the course based on knowledge creation. On the other hand, the results showed the relevance of applying knowledge creation-based learning to the mass teaching of construction in higher education. The findings of this empirical study suggest that more attention should focus on developing students' metacognitive skills in engineering education.

    The extractive and construction industries rely heavily on accurate geospatial data to control position, location, alignment, and orientation of planned excavations. Recent advancements in the survey industry, through the use of terrestrial laser scanning, can now provide engineering teams with three-dimensional (3-D) data in unprecedented detail via georeferenced point clouds. Furthermore, equipment is now available that provides fully mobile automated mapping solutions, independent of satellite positioning, utilizing simultaneous localization and mapping. This paper evaluates the surveying capability of three fully mobile automated mapping solutions against a benchmark laser scanning survey undertaken at the underground Camborne School of Mines Test Mine facility. The study highlights that handheld automated mapping solutions, in which closed-loops can be formed, have the potential to provide quicker data collection and processing time, as well as the required accuracy for underground surveying applications. However, the automated solution was unable to produce the necessary point cloud density to identify low-angled discontinuities that may have a major safety implication, leading to potential rockfall.

    2011-07-01

    In recent years, significant advances have been made in business organization and management. The growing demands of clients as well as the globalization of world markets are among the many factors that have led to the establishment of systems of quality control and environmental management as a competitive strategy for businesses. When compared to other professional sectors, the construction sector has been slower to respond to environmental problems and to adopt Environmental Management Systems (EMS). In the world today the ISO 14001 standard is currently the main frame of reference used by construction companies to implement this type of management system. This article presents the results of a general study regarding the evaluation of the application of the ISO 14001 standard at civil engineering construction worksites in the Community of Madrid (Spain), specifically pertaining to requirement 4.4.1, Resources, roles, responsibilities, and authority. According to requirement 4.4.1, company executives should appoint people responsible for implementing the EMS and also specify their responsibilities and functions. The personnel designated for supervising environmental work should also have sufficient authority to establish and maintain the EMS. The results obtained were the following: - EMS supervisors did not generally possess adequate training and solid experience in construction work and in the environment. Furthermore, supervisors were usually forced to combine their environmental work with other tasks, which made their job even more difficult. - Generally speaking, supervisors were not given sufficient authority and autonomy because productivity at the construction site had priority over environmental management. This was due to the fact that the company management did not have a respectful attitude toward the environment, nor was the management actively involved in the establishment of the EMS. - Insufficient resources were allocated to the Environmental

    In this research, survey of awareness and attitude to high level radioactive waste (HLW) disposal on 36 students of a postgraduate course was conducted. They have been studying civil and rock engineering, so they belong to 'the Group' that acquires high education, culture and faculty to understand the science in geological disposal of HLW. First of all the awareness of danger or safety to HLW disposal was examined. Some 23% regard HLW disposal as safe, on the contrary 60% feel danger. This is similar to the awareness of the average public. And some 72% think that HLW should be disposal, but only 6% agree the repository in their town. It shows that the Group of high education has a tendency of calmly understand the necessity of disposal, but they also have a nature so-called 'not in my back yard (NIMBY)'. After that, the students were divided in two groups. Then, one group received information from the promoter, and another received information from opponents. The result of second questionnaire shows that the awareness of danger is affected strongly by given information even in this Group, but they become thoughtful and prudent in their opinion and decision-making as increasing information. Finally in this paper it is studied that 'what is the role of education of civil engineering?' and 'what is key issue in R and D of HLW disposal?' considering Public Acceptance. (author)

    Producers, authorities and users have acknowledged the need for common environmental guidelines for residues. The objective of this project has been to develop a proposal for common environmental guidelines for reuse of ash in civil engineering applications. The project has a narrow risk assessment perspective and focus on a set of substances where a well developed environmental policy and knowledge are available. Health aspects for construction workers are not covered in the project. The starting point in the risk assessment is the assumption that ashes may be used just like any conventional construction material. Special requirements or regulations regarding precautionary actions in the handling of ashes, regarding the site or surroundings will be avoided. The guiding principle has been the precautionary principle: reuse of ash is acceptable only if it constitute an insignificant risk to health and environment. The calculations are based on defined emission- and exposure scenarios. The concept of insignificant risk imply that the impact in the defined points of compliance does not exceed established health- and environmental criteria. The model address health risks associated with spreading of particles and exposure by dust, oral intake, dermal contact and intake by vegetables or wild grown berries and consumption of ground water. Off-site environmental effects in surface waters and in soil as well as health- and environmental risks in the post use phase are also considered. Exposure by dust is addressed in the same way as in the Swedish Environmental Protection Agency's guidelines for contaminated soil. The guidelines values for exposure by dust, oral intake, dermal contact and intake by vegetables or wild grown berries are total content, whereas the guidelines for exposure by consumption of ground water or environmental effects in surface waters are based on leaching properties of the ash. The guidelines rely on a conceptual model, defined emissions and

    Nowadays, Touro amphibolites (La Coruna, Spain) are exploited as crushed-rock aggregates in civil engineering. These materials are mainly used as ballast for road construction. Therefore, it is interesting to study these materials in function of several parameters obtained directly in quarry faces. For this purpose, the same techniques and tests previously applied in other fields such as natural stone have been used. The aim of this work is to study the quality and durability of Touro amphibolites when subjected to extreme temperature, water and salt (NaCl) actions. The NaCl is included in this study because it is commonly used as fluxing material in pavements and roads. The quality of these amphibolites, a classification based on the concrete and road tests and the techniques applied, is good. The best properties of these materials are their low porosity and high ability to compact. They also have a high durability under the action of extreme temperatures, salts and water. These results also indicate that these amphibolites can better support high temperature rather than low temperature degradation. (Author)

    Full Text Available China’s rapid urbanization has led to increasing steel consumption for buildings and civil engineering infrastructure. The in-use steel stock in the same is considered to be closely related to social welfare and urban metabolism. Traditional approaches for determining the in-use steel stock are labor-intensive and time-consuming processes and always hindered by the availability of statistical data. To address this issue, this study proposed the use of long-term nighttime lights as a proxy to effectively estimate in-use steel stock for buildings (IUSSB and civil engineering infrastructure (IUSSCE at the provincial level in China. Significant relationships between nighttime lights versus IUSSB and IUSSCE were observed for provincial variables in a single year, as well as for time series variables of a single province. However, these relationships were found to differ among provinces (referred to as “inter-individual differences” and with time (referred to as “temporal differences”. Panel regression models were therefore proposed to estimate IUSSB and IUSSCE in consideration of the temporal and inter-individual differences based on a dataset covering 1992–2007. These models were validated using data for 2008, and the results showed good estimation for both IUSSB and IUSSCE. The proposed approach can be used to easily monitor the dynamic of IUSSB and IUSSCE in China. This should be critical in providing valuable information for policy making regarding regional development of buildings and infrastructure, sustainable urban resource management, and cross-boundary material recycling.

    Full Text Available From early times, building and civil engineering construction has been a male dominated industry. But in today’s contemporary times, the women folk have broken this monotony of male domination. This is evident in the building and engineering industry. Isoko land in the south of Delta State, although women have broken from the stereotype of home keeping into construction, their level of engagement is at the lowest ebb as casual and unskilled workers. This study looks at the factors that encourage female to engage in construction especially at the lowest ebb and the implications for the woman, society, and construction industry. Oral interview methodology was adopted in this study. The response of five local contractors/employers and 60 women interviewed at construction site formed the data for this study. A simple percentage was used to analyze data generated. Findings reveal that poverty and unemployment, lack of education and skill, family responsibility and environmental factors top the reasons. Policies that encourage and make it mandatory for women to progress in education and skill acquisition, provide a future for women in construction and stop discrimination against women will be a step in the right direction. Such policies are recommended.

    2016-10-01

    This paper deals with the conditions underlying and the problems arising from the siting of a building with specialist laboratories in a developed part of the university campus in Olsztyn, Poland. The topography of the terrain and the need to house civil engineering laboratories in the planned building had an immense impact on the shape of the building and consequently on its foundations, whose dimensions responded to the ground conditions and the specification of various loads they would have to support, including the equipment for the laboratories. The siting of a building as a step in the construction process entails several problems, which are first taken into consideration at the stage of making preliminary concept plans and are subsequently verified while working on the final construction plan. The required information included geotechnical documentation, survey of the ground conditions and the data regarding the predicted loads on the building, necessary to select the right type of foundations. All these problems grow in importance when dealing with such unique buildings like the discussed example of a laboratory building for the Civil Engineering Department, built on a site within a conservation zone on the campus of the University of Warmia and Mazury in Olsztyn, Poland. The specific character of the building and the specialist equipment with which it was to be furnished (a resistance testing machine, a 17-meter-long wave flume) necessitated a series of analyses prior to the siting of the building and selecting suitable foundations. In turn, the fact that the new building was to be erected in the conservation zone meant that collaboration with the Heritage Conservation Office had to be undertaken at the stage of making the plan and continued during the construction works. The Heritage Officer's recommendations concerning the building's shape, divisions, dimensions, materials used, etc., created a situation where the team of designers and architects had to

    2013-11-01

    Many fluids lab facilities and their associated student experiences were built back in the 1960-1970 time frames. They typically consisted of large facilities that included wind tunnels, flumes, wet wells, pump stations, etc. Today these labs are physically and pedagogically out dated and the need for lab space is forcing the closing of large scale labs. This is the same basic problem within the Swanson School of Engineering at the University of Pittsburgh. Thus we have replaced all the old equipment and lab experiences with small bench top experiments with a focus on applying the large body of knowledge associate with better student learning experiences. This paper will describe the concepts behind the design of the new experiments and the learning improvements discovered as a result of moving from a few large experiments to a larger number of smaller scale experiments.

    The aim of this research was to present a pilot plant for the treatment of stormwater sediments and to compare the decontamination rate to that obtained by landfarming. The possibilities for reuse of the treated sediments in civil engineering are also studied. Four sediments from retention/infiltration ponds or from street sweeping were studied. In each case organic matter (OM), total hydrocarbons (TH) and polycyclic aromatic hydrocarbons (PAH) were measured. Geotechnical tests were carried out to evaluate the reuse possibilities of the treated sediments. Treatment by means of the pilot plant was efficient at reducing TH and PAH concentrations: THs were reduced by 53-97% and PAHs were decreased by 60-95%. By comparison, a reduction of 45-75% in TH concentration is obtained with landfarming, whereas there is no significant decrease in PAHs. Furthermore, geotechnical tests showed that the treated fractions from the pilot plant can be reused as road embankments and as a capping layer. These results are most encouraging and show that stormwater sediments can valuably be reused after treatment in a pilot plant. Landfarming is less efficient but this technique could be used as a pretreatment in the case of high TH pollution.

    Communications between civilizations within our galaxy at the present level of radio engineering is possible, although civilizations must begin to search for each other to achieve this. If an extra-terrestrial civilization possessing a technology at our level wishes to make itself known and will transmit special radio signals to do this, then it can be picked up by us at a distance of several hundreds of light years using already existing radio telescopes and specially built radio receivers. If it wishes, this civilization can also send us information without awaiting our answer.

  15. Knowing more than they can tell: An assessment of genre awareness among students in writing intensive zoology and civil engineering courses

    Science.gov (United States)

    Hanson, Joleen Kidwell

    Developing genre awareness as a means of "learning how to learn" in new writing situations is a goal of four recently proposed writing pedagogies that recognize the context-dependent nature of standards for "good writing" (Devitt, Reiff, and Bawarshi (2004); Beaufort (2007); Johns (2008); Downs and Wardle (2007)). Yet other scholars argue that useful genre knowledge cannot be taught explicitly in the classroom, but must be acquired tacitly through participation in a workplace or other discourse community (Dias et al. (1999); Freedman (1994); Smit (2004)). This qualitative study investigates the range of variability and potential sources of genre awareness among undergraduates who had not received explicit teaching about genre awareness. It presents students' explicit understanding of why particular genre conventions are followed in a particular context by examining what they could tell about learning the advanced lab report in writing-in-the-major courses in either Zoology or Civil Engineering. Research data includes surveys of all students in three courses (n=112), interviews with a subset in each course (n=24) and with all instructors (n=7), samples of graded student lab reports, and classroom observations. Overall, few study participants demonstrated genre awareness as defined by Devitt. Students showed limited awareness of the rhetorical purposes of the advanced lab report and even less awareness of the values and beliefs embedded in its discourse conventions. Disciplinary identification and mentoring experiences were found to be factors that might contribute to the development of genre awareness. Unexpected findings were that some insecure writers showed relatively high overall genre awareness, while some confident writers showed relatively low genre awareness. Further research is needed to refine an assessment instrument that could be readily used by other researchers. However, the instrument for assessing genre awareness that was developed for this project

    Swedish producers, authorities and users have acknowledged the need for common environmental guidelines for residues. The objective of this project has been to develop a proposal for common environmental guidelines for reuse of ash in civil engineering applications. The project has a narrow risk assessment with application on an strictly nearfield, local perspective and focus on a limited set of substances. Health aspects for construction workers are not covered in the project. The starting point in the risk assessment is the assumption that ashes may be used just like any conventional construction material. Special requirements or regulations regarding precautionary actions in the handling of ashes, regarding the site or surroundings will be avoided. The guiding principle has been the precautionary principle: reuse of ash is acceptable only if it constitute an insignificant risk to health and environment. The calculations are based on defined emission- and exposure scenarios. The concept of insignificant risk imply that the impact in the defined points of compliance does not exceed established health- and environmental criteria. The model address health risks associated with spreading of particles and exposure by dust, oral intake, dermal contact and intake by vegetables or wild grown berries and consumption of ground water. Off-site environmental effects in surface waters and in soil as well as health- and environmental risks in the post use phase are also considered. Exposure by dust is addressed in the same way as in the Swedish Environmental Protection Agency's guidelines for contaminated soil [12]. The guidelines values for exposure by dust, oral intake, dermal contact and intake by vegetables or wild grown berrys are total content, whereas the guidelines for exposure by consumption of ground water or environmental effects in surface waters are based on leaching properties of the ash.

  4. From ``wiggly structures'' to ``unshaky towers'': problem framing, solution finding, and negotiation of courses of actions during a civil engineering unit for elementary students

    Science.gov (United States)

    Roth, Wolff-Michael

    1995-12-01

    The present study was designed to investigate problem- and solution-related activity of elementary students in ill-defined and open-ended settings. One Grade 4/5 class of 28 students engaged in the activities of the “Engineering for Children: Structures” curriculum, designed as a vehicle for introducing science concepts, providing ill-defined problem solving contexts, and fostering positive attitudes towards science and technology. Data included video recordings, ethnographic field notes, student produced artefacts (projects and engineering logbooks), and interviews with teachers and observers. These data supported the notion of problems, solutions, and courses of actions as entities with flexible ontologies. In the course of their negotiations, students demonstrated an uncanny competence to frame and reframe problems and solutions and to decide courses of actions of different complexities in spite of the ambiguous nature of (arte)facts, plans, and language. A case study approach was chosen as the literary device to report these general findings. The discussion focuses on the inevitably ambiguous nature of (arte)facts, plans, and language and the associated notion of “interpretive flexibility.” Suggestions are provided for teachers on how to deal with interpretive flexibility without seeking recourse to the didactic approaches of direct teaching. But what happens when problems and solutions are negotiable, when there are no longer isolated problems which one tries to solve but problems which maintain complex linkages with ensembles of other problems and diverse constraints, or when problems and solutions are simultaneously invented?

    This article analyses the penultimate publication in Giorgio Agambens Homo Sacer-series Stasis: Civil War as a Political Paradigm. It compares and contrasts the paradigm of civil war with the preceding paradigm of the exception, and identifies a significant displacement in the relationship between...... civil war and the sovereign state, in spite of Agamben’s insistence on their continuity. Agamben’s decoupling of civil war and the sovereign state facilitates novel political possibilities that unfortunately remain underdeveloped in the book. The article proceeds to develop Agamben’s brief intimations...... of inoperativity towards a concept of destituent power drawing on his other writings. It makes the argument for thinking civil war and inoperativity – stasis and stasis – together to derive a concept of destituent power as a form of revolution against the sovereign state, which does not constitute a new sovereign...

The aim of adopting frame-legislation is to ensure the developement of civil procedures. The Council Regulations no. 44/2001 on the competence, the recognition and the enforcement of judiciary rulings in civil and commercial cases is a “real” Code of civil procedure in this matter, to be applied in the member states, thus ensuring the free circulation of the judiciary rulings according to the principles of mutual recognition, mutual trust and reinforcement of juridical security in the union. The community civil procedural code prevails over the national procedural code. The Regulations ensure the administration of the community justice and through their rules avoid the pronunciation, in the member states, of rulings that are irreconcilable with each other, the direct beneficiaries being legal and natural persons.

    民机在滑跑减速阶段一般会使用发动机的反向推力来提高其减速性能和滑跑安全性,当滑跑速度较低时使用该装置,从发动机排出的向前方喷射的气流存在被发动机重新吸入的可能,该喷流受发动机风扇的压缩做功,喷流的温度比环境温度高,如果此气流被发动机重新吸入,将会导致发动机进气气流的温度畸变,而该畸变将会引起发动机风扇叶片的颤振,影响发动机的寿命和安全性.故对于一个使用涡扇发动机的新型飞机,有必要通过风洞试验来得到其在各工况下的重吸入特性,并且根据其重吸入特性,设定截止使用反推力的滑跑速度.本文主要论述通过风洞试验获得发动机重吸入特性,并且确定反推力使用截止滑跑速度的方法.%For civil aircraft it is common method to use thrust reverser to improve the deceleration and the safety during landing run. However, if the ground running speed of the aircraft is too low, the forward moving plume flow can be re-ingested by the engine. The temperature of the plume flow is much higher than ambient temperature since it gains energy from fan compressor. As a result the re-ingestion may lead to the temperature distortion for inlet flow causing the flutter of the fan blade, thus harming the engine life and safety. Therefore, for a new turbo-fan aircraft it is necessary to obtain the re-ingestion characteristic of the engine through wind tunnel test in order to determine the turn-off speed limit for thrust reverser. This paper mainly states the method to get the A/C's re-ingestion characteristics from the wind tunnel test and acquire the thrust reverser cut-off taxiing speeds.

    This paper concerns the development of an identification method required in determining structural parameter variations for systems subjected to an extended exposure to the environment. The concept of structural identifiability of a large scale structural system in the absence of damping is presented. Three criteria are established indicating that a large number of system parameters (the coefficient parameters of the differential equations) can be identified by a few actuators and sensors. An eight-bay-fifteen-story frame structure is used as example. A simple model is employed for analyzing the dynamic response of the frame structure.

  14. The barbarism of civilization: cultural genocide and the 'stolen generations'.

    Science.gov (United States)

    van Krieken, R

    1999-06-01

    Norbert Elias suggested that 'civilization' involves the transformation of human habitus so that violence of all sorts is gradually subjected to greater and more sophisticated forms of management and control, whereas 'decivilization' encompasses processes which produce an increase in violence and a breakdown in the stability and consistency of on-going social relations. What remains unexplored is the extent to which 'civilizing offensives', the self-conscious attempts to bring about 'civilization', have revolved around essentially violent policies and practices. This paper examines the systematic removal of indigenous Australian children from their families, largely for the social engineering purpose of the gradual and systematic annihilation of Aboriginal cultural identity. At the time, these policies and practices were constructed by most observers as contributing to the 'welfare' of Australian Aborigines, and this intersection of welfare and violence raises the possibility that civilization and decivilization, rather than being different processes which may or may not run alongside each other, interpenetrate each other so that, under certain circumstances, societies are 'barbaric' precisely in their movement towards increasing civilization. It may also be possible to describe the move away from the systematic removal of Aboriginal children since the 1970s as itself part of a civilizing process, an increasing recognition of the human rights of Australian Aborigines and of the inhumanity of those policies and practices. The paper concludes by addressing the implications for theories of civilization and decivilization, as well as more generally for our contemporary understanding of what it means to be a 'civilized' modern citizen.

  17. Re-thinking civil disobedience

    Directory of Open Access Journals (Sweden)

    Theresa Züger

    2013-11-01

    Full Text Available This article points out a struggle of today’s societies with the traditional concepts of civil disobedience and stresses the need for reevaluation of the concept of civil disobedience for policy making and public discourse. Starting with a minimal definition of civil disobedience, the article introduces Hannah Arendt’s approach for a legitimisation of civil disobedience and discusses her ideas for digital actions, which are increasingly framed as digital forms of civil disobedience. Addressing WikiLeaks as an example of digital civil disobedience, the author problematises the internal secrecy of WikiLeaks and the focus on Julian Assange as a single decision-maker. Both aspects challenge Arendt’s understanding of legitimate civil disobedience. Even though traditional criteria of civil disobedience need to be revisited in the digital age, organisations or disobedience actors might themselves in their actions be well-advised to comply with the principles they fight for.

    Bracewell, R. N.

    A list of possible modes of detecting advanced civilizations elsewhere in the universe is provided, including EM Alfven, and gravity waves, matter transfer, and exotica such as tachyons, black hole tunneling, and telepathy. Further study is indicated for low frequency radio wave propagation, which may travel along magnetic fields to reach the earth while laser beams are not favored because of the power needed for transmitting quanta instead of waves. IR, X ray, and UV astronomy are noted to be suitable for detecting signals in those ranges, while Alfven wave communication will be best observed by probes outside the orbit of Jupiter, where local anomalies have less effect. Particle propagation communication is viewed as unlikely, except as a trace of an extinct civilization, but panspermia, which involves interstellar spreading of seeds and/or spores, receives serious attention, as does laser probe or pellet propulsion.

  15. THE POETIC VECTOR OF CIVILIZATION

    Directory of Open Access Journals (Sweden)

    Mikhail Epstein

    2016-01-01

    Full Text Available The article regards poetry as the type of a world view that has profound effect on the social and technical development of civilization. Contrary to popular belief about the decline of poetry in the technological age, poetry, as the desire for imaginative comprehension and transformation of the world, remains the most powerful engine of civilization. There are new, non-linguistic forms of existence of poetry (outside of verses and books that are explored in the article: anthropoeia, biopoeia, kosmopoeia, noopoeia, sociopoeia, technopoeia… For example, the technique is no less metaphorical and symbolic than poetry is, but it embodies the energy of creation not in words, but in the poetically transfigured matter where each element is „playing” with nature, overcomes the force of gravity, the distances of time and space. Tehnopoeia as realized in aviation, rocketry, electronics, Internet, new means of communication, allows to see clearly the invisible, to hear the inaudible, to speak many languages. Technopoeia is the poetic aspect of technology as an activity that implements the creative aspirations of humans and the symbolic vision of the world. The article examines the „physics of poetry,” as it was understood by Surrealists, and shows that the poetic perception of things is not opposed to its utilitarian functions, but both can be harmoniously combined. Contemporatry science and technology aspire to implement a number of fundamental biopoetic and cosmopoetic metaphors: the universe — a computer, a planet — a living organism, the computer — the brain, the Internet — the nervous system, infectious viruses — computer and genes, the language of life — the process of writing… The metaphor becomes an integral part of the scientific outlook and the driving force behind the new discovery. Philology and poetics need to develop new methods of analysis of poetic phenomena as embodied not in verses, but in scientific thinking and

    Henrik Kaare Nielsen

    2008-07-01

    Full Text Available This article discusses the conceptual heterogeneity in the field of ‘civil society’ in the light of a distinction between positions that reflect civil society as a democratic-emancipatory category and positions that consider civil society from the perspective of the state: as an instrumental resource for the technocratic planning of the competitive nation state.The article discusses the implications and perspectives in these two different strategic scenarios for conceptualizing civil society. The argument is made that civil society in relation to democratic citizenship should basically rather be understood as a concept for specific, communicative principles for institutionalizing societal relations and organizing public experience than as an overall concept for third sector organizations.

    Article 162 of this Mexican Code provides, among other things, that "Every person has the right freely, responsibly, and in an informed fashion to determine the number and spacing of his or her children." When a marriage is involved, this right is to be observed by the spouses "in agreement with each other." The civil codes of the following states contain the same provisions: 1) Baja California (Art. 159 of the Civil Code of 28 April 1972 as revised in Decree No. 167 of 31 January 1974); 2) Morelos (Art. 255 of the Civil Code of 26 September 1949 as revised in Decree No. 135 of 29 December 1981); 3) Queretaro (Art. 162 of the Civil Code of 29 December 1950 as revised in the Act of 9 January 1981); 4) San Luis Potosi (Art. 147 of the Civil Code of 24 March 1946 as revised in 13 June 1978); Sinaloa (Art. 162 of the Civil Code of 18 June 1940 as revised in Decree No. 28 of 14 October 1975); 5) Tamaulipas (Art. 146 of the Civil Code of 21 November 1960 as revised in Decree No. 20 of 30 April 1975); 6) Veracruz-Llave (Art. 98 of the Civil Code of 1 September 1932 as revised in the Act of 30 December 1975); and 7) Zacatecas (Art. 253 of the Civil Code of 9 February 1965 as revised in Decree No. 104 of 13 August 1975). The Civil Codes of Puebla and Tlaxcala provide for this right only in the context of marriage with the spouses in agreement.

    In a recent study (Garrett, 2011), I described theoretical arguments and empirical evidence showing how civilization evolution might be considered from a purely physical basis. One implication is that civilization exhibits the property of persistence in its growth. Here, this argument is elaborated further, and specific near-term forecasts are provided for key economic variables and anthropogenic CO2 emission rates at global scales. Absent some external shock, civilization wealth, energy consumption and carbon dioxide emissions will continue to grow exponentially at an average rate of about 2.3% per year.

    2003-09-01

    This paper analyses financial credit in order to re-examine the work of Norbert Elias, particularly his association of interdependency complexity with social discipline, and his approach to contradiction. Following a discussion of these issues, the paper examines Elias's writing on money and explores the emergence of financial credit networks in early modern England. Attention is paid to credit networks and social discipline, to credit and the state, and to the contradictory images associated with the transition to modern cash economies. From one perspective, early modern credit networks might be read as a confirmation of Elias, particularly his argument that interdependency complexity, changing power balances and self-restraint are interwoven. Yet the development of modern cash money raises questions, not just in relation to Elias's treatment of money, but also with regard to his assumptions about social discipline and his approach to ambivalence and contradiction. Drawing on the foregoing discussion, the paper argues that the relation between interdependency complexity and social discipline is contingent and variable, and that interdependency complexity may simultaneously encourage contradictory processes, such as those of civilizing and barbarity.

    Between tests, NASA research engineer Dave Hahne inspects a tenth-scale model of a supersonic transport model in the 30- by 60-Foot Tunnel at NASA Langley Research Center, Hampton, Virginia. The model is being used in support of NASA's High-Speed Research (HSR) program. Langley researchers are applying advance aerodynamic design methods to develop a wing leading-edge flap system which significantly improves low-speed fuel efficiency and reduces noise generated during takeoff operation. Langley is NASA's lead center for the agency's HSR program, aimed at developing technology to help U.S. industry compete in the rapidly expanding trans-oceanic transport market. A U.S. high-speed civil transport is expected to fly in about the year 2010. As envisioned, it would fly 300 passengers across the Pacific in about four hours at Mach 2.4 (approximately 1,600 mph/1950 kph) for a modest increase over business class fares.

Il tratto di cammino insieme.  Civil Ethic and Evangelical Beatitudes ABSTRACT The differences between civil ethic and religious ethic, that the Author defines as constitutional principles and evangelic Beatitudes, are well known: it’s common knowledge that the ones are effective in the earthly life while the others are oriented to the eternal life. Nevertheless the Author argues that they both have a common feature before that last analysis: they cross as principles of continuing opposition to unjust society, to “unlawful law”, to spreading apart between the constitutional and evangelic must be and the legislative being of positive law.KEY-WORDS: Civil Ethic – Constitution – Evangelical Beatitudes – Differences - Common Feature.

    Today, a growing number of teachers are moving beyond the textbook in teaching about the war, and U.S. history more broadly. Teachers are digging directly into primary sources and harnessing technology, all in an attempt to help students better understand the past and bring it to life. Doing so may be especially important with the Civil War,…

    2008-01-01

    What are the principal purposes, goals, and priorities of the U.S. civil space program? This question was the focus of the workshop on civil space policy held November 29-30, 2007, by the Space Studies Board (SSB) and the Aeronautics and Space Engineering Board (ASEB) of the National Research Council (NRC). In addressing this question, invited speakers and panelists and the general discussion from this public workshop explored a series of topics, including the following: (1) Key changes and developments in the U.S. civil space program since the new national Vision for Space Exploration2 (the Vision) was articulated by the executive branch in 2004; (2) The fit of space exploration within a broader national and international context; (3) Affordability, public interest, and political will to sustain the civil space program; (4) Definitions, metrics, and decision criteria for the mix and balance of activities within the program portfolio; (5) Roles of government in Earth observations from space; and (6) Gaps in capabilities and infrastructure to support the program.

    The manifestations of climate change can result in humanitarian impacts that reverse progress in poverty- reduction, create shortages of food and resources, lead to migration, and ultimately result in civil violence and conflict. Within the continent of Africa, we have found that environmentally-related variables are either the cause or the confounding factor for over 80% of the civil violence events during the last 10 years. Using predictive climate models and land-use data, we are able to identify populations in Africa that are likely to experience the most severe climate-related shocks. Through geospatial analysis, we are able to overlay these areas of high risk with assessments of both the local population's resiliency and the region's capacity to respond to climate shocks should they occur. The net result of the analysis is the identification of locations that are becoming particularly vulnerable to future civil violence events (vulnerability hotspots) as a result of the manifestations of climate change. For each population group, over 600 social, economic, political, and environmental indicators are integrated statistically to measures the vulnerability of African populations to environmental change. The indicator time-series are filtered for data availability and redundancy, broadly ordered into four categories (social, political, economic and environmental), standardized and normalized. Within each category, the dominant modes of variability are isolated by principal component analysis and the loadings of each component for each variable are used to devise composite index scores. Comparisons of past vulnerability with known environmentally-related conflicts demonstrates the role that such vulnerability hotspot maps can play in evaluating both the potential for, and the significance of, environmentally-related civil violence events. Furthermore, the analysis reveals the major variables that are responsible for the population's vulnerability and therefore

  10. Global civil aviation black carbon emissions.

    Aircraft black carbon (BC) emissions contribute to climate forcing, but few estimates of BC emitted by aircraft at cruise exist. For the majority of aircraft engines the only BC-related measurement available is smoke number (SN)-a filter based optical method designed to measure near-ground plume visibility, not mass. While the first order approximation (FOA3) technique has been developed to estimate BC mass emissions normalized by fuel burn [EI(BC)] from SN, it is shown that it underestimates EI(BC) by >90% in 35% of directly measured cases (R(2) = -0.10). As there are no plans to measure BC emissions from all existing certified engines-which will be in service for several decades-it is necessary to estimate EI(BC) for existing aircraft on the ground and at cruise. An alternative method, called FOX, that is independent of the SN is developed to estimate BC emissions. Estimates of EI(BC) at ground level are significantly improved (R(2) = 0.68), whereas estimates at cruise are within 30% of measurements. Implementing this approach for global civil aviation estimated aircraft BC emissions are revised upward by a factor of ~3. Direct radiative forcing (RF) due to aviation BC emissions is estimated to be ~9.5 mW/m(2), equivalent to ~1/3 of the current RF due to aviation CO2 emissions.

  9. Designs and Technology Requirements for Civil Heavy Lift Rotorcraft

    Science.gov (United States)

    Johnson, Wayne; Yamauchi, Gloria K.; Watts, Michael E.

    2006-01-01

    The NASA Heavy Lift Rotorcraft Systems Investigation examined in depth several rotorcraft configurations for large civil transport, designed to meet the technology goals of the NASA Vehicle Systems Program. The investigation identified the Large Civil Tiltrotor as the configuration with the best potential to meet the technology goals. The design presented was economically competitive, with the potential for substantial impact on the air transportation system. The keys to achieving a competitive aircraft were low drag airframe and low disk loading rotors; structural weight reduction, for both airframe and rotors; drive system weight reduction; improved engine efficiency; low maintenance design; and manufacturing cost comparable to fixed-wing aircraft. Risk reduction plans were developed to provide the strategic direction to support a heavy-lift rotorcraft development. The following high risk areas were identified for heavy lift rotorcraft: high torque, light weight drive system; high performance, structurally efficient rotor/wing system; low noise aircraft; and super-integrated vehicle management system.

    Full Text Available Objective: The risks in unmanned civil aviation are considered as one of the most important. In the article is proved applicability of ensuring the flight safety of aircraft and considered the basic risks of manned civil aviation. Methods: Analyzed statistical data on aviation accidents, organized probabilities distribution of aviation accidents for manned and unmanned civil aviation to identify factors that influence the occurrence of emergency situations in manned and unmanned aviation. Results: We proposed typology of risk components in civil aviation and systematized methods and techniques to reduce risks. Over the analogies defined possible risks, their causes and remedies in civil unmanned aircraft. Weight coefficients distribution was justified between risk types for development of recommendations on risk management in unmanned civil aviation. Discussion: We found that the most probable risk in manned civil aviation is the human factor, organization of air traffic control, design flaws of unmanned aviation system as a whole, as well as maintenance of unmanned aviation system.

    The author examines how Bioethics should be approached in a pluralist society. She argues that through the gradual discovery of shared ethical values and principles for judging which practices are humanizing and which or not, ever-more dense civil Bioethics helps bring out--in contrast to relativism and subjectivism--an ethical intersubjectiveness, the fundaments of which should be addressed by moral philosophy if it hopes to fulfill one of its main tasks.

  13. The Celestial Basis of Civilization

    Science.gov (United States)

    Masse, W. B.

    Scholars have long puzzled over the reasons for the ubiquity of celestial images in the residue of the world's earliest civilizations: in art, myth, religious cosmology, iconography, cosmogony, eschatological beliefs, and as portents for the conduct of royal and chiefly power. The general consensus is that these images represented a need by early societies to use the fixed celestial heavens in order to regulate ritual and agricultural cycles, and to satisfy a psychological need by people to relate themselves to their surrounding Universe. Such explanations are facile and miss an important aspect of the celestial heavens. The fixed celestial heavens served as the back-drop for a large number of often spectacular temporary naked-eye visible celestial events which animated the night and sometimes the daytime sky, and which created an 'otherworld' for virtually all cultural groups. In this paper I present a model derived from the detailed analysis of Hawaiian oral traditions and culture history in relation to historic astronomical records of temporary celestial events, and then apply this model to cultural traditions from Mesoamerica and other geographic regions in order to demonstrate that novae, supernovae, variable stars, comets, great meteor showers, aurorae, solar and lunar eclipses, and impacting Solar System debris, together played a critical role in the artistic, intellectual, and political development of early civilizations. These data not only provide important insights into the development of civilization, but also provide important details and longitudinal records of astronomical events and phenomena which are otherwise not readily available for scientific scrutiny.

    abstract The development and utilization of underground spaces are heavily limited by actual conditions and regulations for fire prevention. The depth of underground spaces, which is over 10 meters, cannot be applied to commercial development due to the problem of personnel emergency evacuation. This paper takes Qingdao underground civil air defense engineering as an example, in which the underground space is buried more than 10 meters depth, with contradiction between the need for crowd escape and high level of elevation difference. This example integrates elevator and stair evacuation, forming an evacuation complex, namely "body vertical evacuation". For the safety evacuation design of super deep underground space, it provides a new train of thought, and enriches the theory of safe evacuation design.%由于自然条件、防火规范的限制,深于10m的地下空间的开发利用面临一个技术瓶颈,即受限于人员应急疏散问题而无法进行商业开发。以青岛某地下人防工程为例,为了解决埋深大于10m的地下公共空间中逃生人数多与垂直高差大的矛盾,考虑将疏散电梯与楼梯整合,形成疏散综合体,即“垂直疏散体”,旨在从建筑设计层面为超深地下公共空间的安全疏散设计提供新的思路,丰富其安全疏散设计的理论。

In the process of teaching, students study by video out-side class and teachers organize interactive seminar in class. Stu-dents are guided to independent learning, so their theoretical knowledge system is reinforced by the analysis and discussion of the actual project cases. The teaching practice shows that stu-dents' learning interest is significantly improved and innovation ability is developed well. Therefore, this teaching model plays a good demonstration effect for other courses' teaching reform.

    2010-05-01

    This paper reviews different approaches of collaboration with the Civil Protection across Europe, from the experience of the author. The first contact came working as a research assistant at the Universität Karlsruhe (TH), Germany, in frame of the SFB (Collaborative Research Centre) 461 "Strong earthquakes", which featured a collaboration Germany-Romania. The subproject C7, where involved, about Novel Rescue technologies was a collaboration between the Institute for Technology and Management in Construction, formerly Institute for Construction Management and Machinery, and the Romanian Civil Protection. The scientific results of the project were to be lated implemented by the Civil Protection. In course of the work contacts were done also through the work of the research associate, sub-project leader, in the THW (German Technical Assistance). Later on work continued at the same institute but in frame of the Research Training Network "Natural Disasters" when also contacts with the Romanian representative to the European Earthquake Engineering Association, were established. Working further in the same field of Natural Disasters, especially seismic risk, brought the author to the ROSE School in Pavia, Italy, researches of which closely collaborate with the EUCENTRE, founded, among other institutions, by the Italian Civil Protection. Particularly the collaboration with specialists from the Italian Civil Protection resulted in several initiatives, such as: - paper contribution to a special issue edited by the author, - organisation of EGU sessions on the topic of "Natural Hazards' Impact on Urban Areas and Infrastructure", - invited review of papers, - attendance of short course coordinated at the ROSE School on post-earthquake safety assessment, - ellaboration of scientific projects submitted for funding on the topic of earthquake hazard impact at various geographic scales, - further publication collaborations are in work, - it is intended to improve the collaboration

    How should we understand Gandhi’s commitment to nonviolence?After discussing and refuting the idea that Gandhi’s conceptionof non-violence can be treated merely as a method to stand up toaggression, its embedment in a concept of true civilization is examined. It is argued that the important nuances between the definitions of civilization in the Gujarati and the English versions of Gandhi’s seminal work Hind Swaraj (1909) reveal Gandhi’s conception of civilization.

  7. Direct carbon dioxide emissions from civil aircraft

    Grote, Matt; Williams, Ian; Preston, John

    2014-10-01

    Global airlines consume over 5 million barrels of oil per day, and the resulting carbon dioxide (CO2) emitted by aircraft engines is of concern. This article provides a contemporary review of the literature associated with the measures available to the civil aviation industry for mitigating CO2 emissions from aircraft. The measures are addressed under two categories - policy and legal-related measures, and technological and operational measures. Results of the review are used to develop several insights into the challenges faced. The analysis shows that forecasts for strong growth in air-traffic will result in civil aviation becoming an increasingly significant contributor to anthropogenic CO2 emissions. Some mitigation-measures can be left to market-forces as the key-driver for implementation because they directly reduce airlines' fuel consumption, and their impact on reducing fuel-costs will be welcomed by the industry. Other mitigation-measures cannot be left to market-forces. Speed of implementation and stringency of these measures will not be satisfactorily resolved unattended, and the current global regulatory-framework does not provide the necessary strength of stewardship. A global regulator with ‘teeth' needs to be established, but investing such a body with the appropriate level of authority requires securing an international agreement which history would suggest is going to be very difficult. If all mitigation-measures are successfully implemented, it is still likely that traffic growth-rates will continue to out-pace emissions reduction-rates. Therefore, to achieve an overall reduction in CO2 emissions, behaviour change will be necessary to reduce demand for air-travel. However, reducing demand will be strongly resisted by all stakeholders in the industry; and the ticket price-increases necessary to induce the required reduction in traffic growth-rates place a monetary-value on CO2 emissions of approximately 7-100 times greater than other common

    Connor, Jerome J

    2013-01-01

    Fundamentals of Structural Engineering provides a balanced, seamless treatment of both classic, analytic methods and contemporary, computer-based techniques for conceptualizing and designing a structure. The book’s principle goal is to foster an intuitive understanding of structural behavior based on problem solving experience for students of civil engineering and architecture who have been exposed to the basic concepts of engineering mechanics and mechanics of materials. Making it distinct from many other undergraduate textbooks, the authors of this text recognize the notion that engineers reason about behavior using simple models and intuition they acquire through problem solving. The approach adopted in this text develops this type of intuition  by presenting extensive, realistic problems and case studies together with computer simulation, which allows rapid exploration of  how a structure responds to changes in geometry and physical parameters. This book also: Emphasizes problem-based understanding of...

  13. The Importance of Thermal Heat Bridges in Civil Engineering

    Directory of Open Access Journals (Sweden)

    Adriana Tokar

    2011-10-01

    Full Text Available Based on the heat transfer characteristics of a construction, the expected temperatures along interior surfaces must be evaluated in order to predict (and avoid areas of potential moisture condensation. Beyond preventing damage to building materials caused by mould growth, adequate surface temperatures are also a relevant factor in the thermal comfort of an interior environment. An agreable climate in a room can be obtained, when relative humidity is between 40 and 60%. As the air in a room is warmer, the more vapor can absorb (and vice versa, influencing the thermal comfort index. Heat losses are influenced largely by thermal bridges of construction. The importance of the thermal heat bridges is strongly increasing today. In new developments the thermal optimization of junctions in today common low energy constructions receives very special standing. The subject of avoiding thermal bridges in passive houses became predominant.

    Möller, Bernd

    2004-01-01

    This book, for the first time, provides a coherent, overall concept for taking account of uncertainty in the analysis, the safety assessment, and the design of structures. The reader is introduced to the problem of uncertainty modeling and familiarized with particular uncertainty models. For simultaneously considering stochastic and non-stochastic uncertainty the superordinated uncertainty model fuzzy randomness, which contains real valued random variables as well as fuzzy variables as special cases, is presented. For this purpose basic mathematical knowledge concerning the fuzzy set theory and the theory of fuzzy random variables is imparted. The body of the book comprises the appropriate quantification of uncertain structural parameters, the fuzzy and fuzzy probabilistic structural analysis, the fuzzy probabilistic safety assessment, and the fuzzy cluster structural design. The completely new algorithms are described in detail and illustrated by way of demonstrative examples.
