Available in PDF, EPUB and Kindle. Book excerpt: 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 techniques for repairing structures that have suffered damage during past events, or for structures that have been found in need of strengthening; development of new design provisions that consider multiple hazards, as well as questions from law and the humanities relevant to the management of natural and human-made hazards.

Download or read book Role of Seismic Testing Facilities in Performance Based Earthquake Engineering written by Michael N. Fardis and published by Springer Science & Business Media. This book was released on 2011-10-07 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nowadays research in earthquake engineering is mainly experimental and in large-scale; advanced computations are integrated with large-scale experiments, to complement them and extend their scope, even by coupling two different but simultaneous tests. Earthquake engineering cannot give answers by testing and qualifying few, small typical components or single large prototypes. Besides, the large diversity of Civil Engineering structures does not allow drawing conclusions from only a few tests; structures are large and their seismic response and performance cannot be meaningfully tested in an ordinary lab or in the field. So, seismic testing facilities should be much larger than in other scientific fields; their staff has to be resourceful, devising intelligent ways to carry out simultaneously different tests and advanced computations. To better serve such a mission European testing facilities and researchers in earthquake engineering have shared their resources and activities in the framework of the European project SERIES, combining their research and jointly developing advanced testing and instrumentation techniques that maximize testing capabilities and increase the value of the tests. This volume presents the first outcomes of the SERIES and its contribution towards Performance-based Earthquake Engineering, i.e., to the most important development in Earthquake Engineering of the past three decades. The concept and the methodologies for performance-based earthquake engineering have now matured. However, they are based mainly on analytical/numerical research; large-scale seismic testing has entered the stage recently. The SERIES Workshop in Ohrid (MK) in Sept. 2010 pooled together the largest European seismic testing facilities, Europe’s best experts in experimental earthquake engineering and select experts from the USA, to present recent research achievements and to address future developments. Audience: This volume will be of interest to researchers and advanced practitioners in structural earthquake engineering, geotechnical earthquake engineering, engineering seismology, and experimental dynamics, including seismic qualification.
Download or read book Testing and Analysis of Structural Steel Columns Subjected to Blast Loads written by Lauren K. Stewart and published by . This book was released on 2010 with total page 890 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extreme loading conditions generated by blasts that result from terrorist attacks can cause devastating consequences for structures and their occupants. In steel frame structures, the damage and failure of a structural column from a blast load can result in a progressive collapse and catastrophic failure of the entire structure. The objectives of this dissertation were to develop experimental methodologies, analysis strategies and threat assessment tools that can be used to mitigate blast hazards and predict damage in structural steel frame structures. Typically, guidelines and methodologies are developed from conclusions drawn via field testing with live explosives, but due to the harsh environment created by explosives, collecting reliable data is problematic. In an effort to provide key answers to questions related to how structures behave during these types of explosions, the University of California, San Diego Blast Simulator was developed. The Blast Simulator consists of ultra-high speed actuators that accelerate/decelerate impacting modules toward the specimen in a controlled manner. Utilizing the transfer of momentum and energy of masses at high velocities, blast-like loads are applied to the structure without the use of explosive materials. Since no fireball is generated, specimen behavior can be observed for the full duration of the loading using high-speed photography. For this dissertation, experiments were conducted with the Blast Simulator to study the effects of impulsive loading on typical steel W-Shapes. The objectives of the dissertation were met through an experimental and computational effort that included the characterization of column behavior, development of a testing protocol for loading of columns in both weak and strong axis directions, validation and implementation of numerical models to predict loads delivered to specimens as well as column behavior and generation of relations pertaining to Simulator operation. Finally, the validated finite element models were incorporated into the development of a fast running, threat assessment tool using an artificial neural network that can predict the residual capacity of a blast damaged column. The fast running model allows for the analysis of steel structures in situations where a time consuming computational model may not be efficient.
Download or read book Design of High Strength Steel Reinforced Concrete Columns written by Sing-Ping Chiew and published by CRC Press. This book was released on 2018-04-17 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the companion volume to Design Examples for High Strength Steel Reinforced Concrete Columns – A Eurocode 4 Approach. Guidance is much needed on the design of high strength steel reinforced concrete (SRC) columns beyond the remit of Eurocode 4. Given the much narrower range of permitted concrete and steel material strengths in comparison to EC2 and EC3, and the better ductility and buckling resistance of SRC columns compared to steel or reinforced concrete, there is a clear need for design beyond the guidelines. This book looks at the design of SRC columns using high strength concrete, high strength structural steel and high strength reinforcing steel materials – columns with concrete cylinder strength up to 90 N/mm2, yield strength of structural steel up to 690 N/mm2 and yield strength of reinforcing steel up to 600 N/mm2 respectively. The companion volume provides detailed worked examples on use of these high strength materials. This book is written primarily for structural engineers and designers who are familiar with basic EC4 design, and should also be useful to civil engineering undergraduate and graduate students who are studying composite steel concrete design and construction. Equations for design resistances are presented clearly so that they can be easily programmed into design spreadsheets for ease of use.

This book was released on 2018-04-17 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the companion volume to Design of High Strength Steel Reinforced Concrete Columns – A Eurocode 4 Approach. This book provides a large number of worked examples for the design of high strength steel reinforced concrete (SRC) columns. It is based on the Eurocode 4 approach, but goes beyond this to give much needed guidance on the narrower range of permitted concrete and steel material strengths in comparison to EC2 and EC3, and the better ductility and buckling resistance of SRC columns compared to steel or reinforced concrete. Special considerations are given to resistance calculations that maximize the full strength of the materials, with concrete cylinder strength up to 90 N/mm2, yield strength of structural steel up to 690 N/mm2 and yield strength of reinforcing steel up to 600 N/mm2 respectively. These examples build on the design principles set out in the companion volume, allowing the readers to practice and understand the EC4 methodology easily. Structural engineers and designers who are familiar with basic EC4 design should find these design examples particularly helpful, whilst engineering undergraduate and graduate students who are studying composite steel concrete design and construction should easily gain further understanding from working through the worked examples which are set out in a step-by-step clearly fashion.
Download or read book Design Against Blast written by S. Syngellakis and published by WIT Press. This book was released on 2013 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: Terrorist attacks and other destructive incidents caused by explosives have, in recent years, prompted considerable research and development into the protection of structures against blast loads. For this objective to be achieved, experiments have been performed and theoretical studies carried out to improve our assessments of the intensity as well as the space-time distribution of the resulting blast pressure on the one hand and the consequences of an explosion to the exposed environment on the other.This book aims to enhance awareness on and understanding of these topical issues through a collection of relevant, Transactions of the Wessex Institute of Technology articles written by experts in the field. The book starts with an overview of key physics-based algorithms for blast and fragment environment characterisation, structural response analyses and structural assessments with reference to a terrorist attack in an urban environment and the management of its inherent uncertainties.A subsequent group of articles is concerned with the accurate definition of blast pressure, which is an essential prerequisite to the reliable assessment of the consequences of an explosion. Other papers are concerned with alternative methods for the determination of blast pressure, based on experimental measurements or neural networks. A final group of articles reports investigations on predicting the response of specific structural entities and their contents.The book concludes with studies on the effectiveness of steel-reinforced polymer in improving the performance of reinforced concrete columns and the failure mechanisms of seamless steel pipes used in nuclear industry.

Download or read book Effect of High Performance Steel Materials on the Blast Behaviour of Ultra High Performance Concrete Columns written by Sarah De Carufel and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Previous events have demonstrated the vulnerability of reinforced concrete infrastructure to blast loading. In buildings, ground-story columns are key structural components, and their failure can lead to extensive damages which can cause progressive collapse. To prevent such disasters, the steel reinforcement in such columns must be properly detailed to ensure sufficient strength and ductility. The use of modern concrete materials such ultra-high performance concrete (UHPC) is one potential solution to improve the blast performance of columns. UHPC shows high compressive strength, high tensile resistance and superior toughness, properties which make it ideal for use in the blast-resistant design of columns. The combined use of UHPC and high-performance steels can potentially be used to further enhance the blast resistance of columns. This thesis presents an experimental and analytical study which investigated the use of high-performance materials to increase the blast capacity and ductility of reinforced concrete columns. As part of the experimental study, a total of seventeen columns were tested under simulated blast loading using the University of Ottawa Shock-Tube. Parameters investigated included the effect of concrete type (NSC and UHPC), steel reinforcement type (normal-strength, high-strength or highly ductile), longitudinal reinforcement ratio, seismic detailing and fiber properties. The test program included two control specimens built with normal-strength concrete, five specimens built with UHPC in combination with high-strength steel, and ten columns built with highly ductile stainless steel reinforcement. Each column was subjected to a series of increasing blast pressures until failure. The performance of the columns is investigated by comparing the displacements, impulse capacity and secondary fragmentation resistance of the columns. The results show that using high-performance steels increases the blast performance of UHPC columns. The use of sufficient amounts of high-strength steel in combination with UHPC led to important increases in column blast capacity. The use of ductile stainless steel reinforcement allowed for important enhancements in column ductility, with an ability to prevent rupture of tension steel reinforcement. The study also shows that increasing the longitudinal reinforcement ratio is an effective means of increasing the blast resistance of UHPC columns The thesis also presents an extensive analytical study which aimed at predicting the response of the test columns using dynamic inelastic, single-degree-of-freedom (SDOF) analysis. A sensitivity analysis was also performed to examine the effect of various modelling parameters on the analytical predictions. Overall, it was shown that SDOF analysis could be used to predict the blast response of UHPC columns with reasonable accuracy. To further corroborate the results from the experimental study, the thesis also presents an analytical parametric study examining the blast performance of larger-scale columns. The results further demonstrate the benefits of using UHPC and high-performance steel reinforcement in columns subjected to blast loading.

Download or read book Reliability of Steel Columns Protected by Intumescent Coatings Subjected to Natural Fires written by Chao Zhang and published by Springer. This book was released on 2016-10-29 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis studied the effect of aging of intumescent coatings (ICs) on the reliability of protected steel columns in fire condition and developed a probabilistic approach to assess the service life of ICs applied on steel columns. In the study, Monte Carlo simulations were conducted to obtain the reliability index or failure probability of steel columns protected by ICs subjected to compartment fires. The effect of aging of intumescent coatings on the failure probability of protected steel columns was investigated by using variable insulation property of intumescent coatings in the simulation. The test data on aging effect on insulation property of intumescent coatings from literature was used. Based on the reliability analysis, a probabilistic approach is given to determine the service life of intumescent coatings for steel columns. In that approach, the failure probability of the protected steel columns is compared with the target probability of the structural fire design. The approach can also be used for probabilistic analysis of steel columns protected by conventional inert fire protection materials.
