Available in PDF, EPUB and Kindle. Book excerpt: Progressive collapse is a situation when one or more key structural elements fail resulting in the failure of adjoining structural elements and, in return, leading to partial or total collapse of the entire building. One method of reducing the likelihood of a progressive collapse situation is to have structures designed with high redundancy so that a higher level of force distribution can take place after the failure of key structural elements. For an accurate evaluation of the structural behavior in a progressive collapse scenario, a nonlinear dynamic analysis (NDA) that considers the geometric and material nonlinearity should be conducted. The goal of this evaluation is to assess whether or not the structure is likely to collapse. The procedure of performing nonlinear dynamic analysis to design structures to resist progressive collapse is complicated; therefore, engineers usually perform simplified static analyses as opposed to conducting computationally expensive dynamic analyses. Codes such as General Service Administration (GSA2003), Department of Defense (DoD2005), and Unified Facilities Criteria (UFC2009) allow three types of analysis in the alternate path method: linear static (LSA), nonlinear static (NSA), and NDA. In LSA and NSA, for considering the dynamic amplification effect, gravity loads are increased using a load increase factor (LIF). LIF is equal to two for LSA and NSA, based on GSA2003 and DoD2005. In UFC2009 and GSA2013, the LIF is calculated using code equations. Previous studies show these coefficients are very conservative. Finding the optimal load increase factor (LIF) for both LSA and NSA would be more cost effective in the design of structures to help them resist progressive collapse. In this study, by considering effective variables, the researcher attempted to find an optimal and reliable LIF for steel buildings.

This book was released on 2024-09-21 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the notorious terrorist attack of the World Trade Center in 2001, researchers and engineers have been forced to review the existing research works and standards in resisting the progressive collapse of structures. From then on, the design of structure against progressive collapse has tended toward quantitative design, rather than qualitative design. The collapse of the COVID-19 epidemic isolation hotel in Quanzhou, China, in 2020 and the vertical collapse of a 12-story apartment in Florida, United States, in 2021 have aroused an upsurge of the research on progressive collapse. More experimental and theoretical works have been focused on this area. This book addresses this issue and provides a valuable reference for the progressive collapse analysis and design of building structures. - Reviews latest references systematically in terms of experiments, simulation, and theory - Introduces different test equipment used in the tests of progressive collapse and also modeling techniques used in the numerical studies of progressive collapse - Includes performance prediction theories used in the analysis of progressive collapse - Comprises considerable information on the tests and simulation and theoretical studies collected from the authors' research in the last 10 years

Available in PDF, EPUB and Kindle. Book excerpt: An understanding of dynamic effects on structures is critical to minimize losses from earthquakes and other hazards. These three books provide an overview of essential topics in structural and geotechnical engineering with an additional focus on related topics in earthquake engineering to enable readers gain such an understanding. One of the ultimate objectives of these books is to provide readers with insights into seismic analysis and design. However, in order to accomplish that objective, background material on structural and geotechnical engineering is necessary. Hence the first two sections of the book provide this background material followed by selected topics in earthquake engineering. The material is organized into three major parts. The first section covers topics in structural engineering. Beginning with fundamental mechanics of materials, the book includes chapters on linear and nonlinear analysis as well as topics on modeling of structures from different perspectives. In addition to traditional design of structural systems, introductions to important concepts in structural reliability and structural stability are discussed. Also covered are subjects of recent interest, viz., blast and impact effects on structures as well as the use of fiber reinforced polymer composites in structural applications. Given the growing interest in urban renewal, an interesting chapter on restoration of historic cities is also included. The second part of the book covers topics in geotechnical engineering, covering both shallow and deep foundations and issues and procedures for geotechnical modeling. The final part of the book focuses on earthquake engineering with emphasis on both structures and foundations. Here again, the material covered includes both traditional seismic design and innovative seismic protection. And more importantly, concepts in modeling for seismic analysis are highlighted.

This book was released on 1999-01-01 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prepared by the Task Committee on Structural Design for Physical Security of the Structural Engineering Institute of ASCE. This report provides guidance to structural engineers in the design of civil structures to resist the effects of terrorist bombings. As dramatized by the bombings of the World Trade Center in New York City and the Murrah Building in Oklahoma City, civil engineers today need guidance on designing structures to resist hostile acts. The U.S. military services and foreign embassy facilities developed requirements for their unique needs, but these the documents are restricted. Thus, no widely available document exists to provide engineers with the technical data necessary to design civil structures for enhanced physical security. The unrestricted government information included in this report is assembled collectively for the first time and rephrased for application to civilian facilities. Topics include: determination of the threat, methods by which structural loadings are derived for the determined threat, the behavior and selection of structural systems, the design of structural components, the design of security doors, the design of utility openings, and the retrofitting of existing structures. This report transfers this technology to the civil sector and provides complete methods, guidance, and references for structural engineers challenged with a physical security problem.

Download or read book Engineering for Extremes written by Mark G. Stewart and published by Springer Nature. This book was released on 2021-12-16 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: The volume explains how risk and decision-making analytics can be applied to the wicked problem of protecting infrastructure and society from extreme events. There is increasing research that takes into account the risks associated with the timing and severity of extreme events in engineering to reduce the vulnerability or increase the resiliency of infrastructure. "Engineering for extremes" is defined as measures taken to reduce the vulnerability or increase the resiliency of built infrastructure to climate change, hurricanes, storms, floods, earthquakes, heat waves, fires, and malevolent and abnormal events that include terrorism, gas explosions, vehicle impact and vehicle overload. The book introduces the key concepts needed to assess the economic and social well-being risks, costs and benefits of infrastructure to extreme events. This includes hazard modelling (likelihood and severity), infrastructure vulnerability, resilience or exposure (likelihood and extent of damage), social and economic loss models, risk reduction from protective measures, and decision theory (cost-benefit and utility analyses). Case studies authored by experts from around the world describe the practical aspects of risk assessment when deciding on the most cost-efficient measures to reduce infrastructure vulnerability to extreme events for housing, buildings, bridges, roads, tunnels, pipelines, and electricity infrastructure in the developed and developing worlds.

This book was released on 2022-02-18 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: Behaviour of Building Structures Subjected to Progressive Collapse gives in-depth and up-to-date quantitative and numerical analysis of building structures against progressive collapse. It does so at various levels, including bare steel joints, composite joints and sub-assemblages and frames under quasi-static loading conditions. The book provides analysis of the force transfer mechanisms of composite structures and reinforced concrete structures, along with detailed numerical models that shed light on the effects of critical parameters on progressive collapse resistances. It includes direct design methods that take into account various collapse-resisting mechanisms. The collapse of the World Trade Center in New York has spurred extensive experimental study and numerical analysis of the structural behavior of buildings under progressive collapse scenarios. Although design guidelines have been published by governments, most are missing up-to-date numerical and experimental results, quantitative accounts of force transfer mechanisms, and numerical guidelines. - Offers in-depth analysis and numerical modeling for building structures against progressive collapse - Provides analysis of the force-transfer mechanisms of composite and reinforced concrete structures - Gives detailed numerical models that shed light on the effects of critical parameters on progressive resistances - Includes direct design methods that take into account various collapse resisting mechanisms - Offers a comprehensive reference for progressive collapse analysis and the design of building structures
