Book Description
During the last two decades, a significant number of embassies, commercial centers, governmental structures, industrial facilities, and residential buildings have been attacked by explosives. Consequently, blast-resistant design of structures has gained importance in recent years to minimize structural damage and threat to life safety. Some guidelines have been developed for this purpose, based on previously conducted research. The U.S. General Services Administration (GSA) report is one of these guidelines that provide practical solutions to blast-related engineering problems, including requirements for analysis and design for prevention of progressive collapse in structures. The guidelines also help establish the potentials for progressive collapse in existing buildings.

Book Description
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

Book Description
Provides a new method for analysing collapse behaviours of buildings under various scenarios, such as impact, fire, blast demolition, earthquake, and tsunami. The analysis of the vulnerability of buildings against progressive collapse is a challenging task. Progressive Collapse of Structures: Numerical Codes and Applications provides a variety of numerical analysis tools and methods which allow engineers to simulate structural collapse behavior during all stages of the process. This book covers methods such as adaptively shifted integration (ASI) and ASI-Gauss techniques. Algorithms are supplied to simulate member fracture and contact behaviors. The author also supplies various numerical examples including case studies from the World Trade Center (WTC) towers in New York City, Nuevo Leon buildings in Mexico, and the collapse of the Canterbury Television (CTV) building in New Zealand. Discusses algorithms for simulating fracture and contact behaviors of structural members Covers fire-induced progressive collapse analyses of high-rise towers, seismic pounding analysis of adjacent buildings, blast demolition analysis of steel-framed structures, and many more Includes numerical codes that supply highly accurate solutions with less memory use and small computational cost

Book Description
Explosion Hazards and Evaluation presents the principles and applications of explosion hazards evaluation. The text is organized into nine chapters. Chapters 1 and 2 discuss the energy release processes which generate accidental explosions, and the resulting development of pressure and shock waves in a surrounding atmosphere. The manner in which the "free-field" waves are modified in interacting with structures or other objects in their paths is discussed in Chapter 3. Structural response to blast loading and non-penetrating impact is covered in two chapters, with Chapter 4 including simplified analysis methods and Chapter 5 including numerical methods. Chapter 6 includes a rather comprehensive treatment of generation of fragments and missiles in explosions, and the flight and effects of impact of these objects. Chapter 7 considers thermal radiation of large chemical explosions. Explosions may or may not cause damage or casualty, and various damage criteria have been developed for structures, vehicles, and people. These criteria are presented in Chapter 8. General procedures for both the postmortem evaluation of accidental explosions and for design for blast and impact resistance are reviewed in Chapter 9. Engineers, scientists, and plant safety personnel will find the book very useful.

Book Description
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.

Book Description
Abstract: The term 'progressive collapse' can be simply defined as the ultimate failure or proportionately large failure of a portion of a structure due to the spread of a local failure from element to element throughout the structure. Progressive collapse can be triggered by manmade, natural, intentional, or unintentional causes. Fires, explosions, earthquakes, or anything else causing large amounts of stress and the failure of a structure's support elements can lead to a progressive collapse failure. Progressive collapse is a complicated dynamic process where the collapsing system redistributes the loads in order to prevent the loss of critical structural members. For this reason beams, columns, and frame connections must be designed in a way to handle the potential redistribution of large loads. Some of the more famous examples of progressive collapse phenomena include the collapse of the World Trade Center towers due to terrorist attack, the bombing of the Murrah Federal Building in Oklahoma City, and the collapse of the Ronan Point building due to a gas explosion. Through research being done, such as that in this study, progressive collapse can be better prepared for and possibly prevented in the future. This project involves use of two main computer programs to perform analysis on a reinforced concrete structure. MATLAB and SAP2000 are used to determine the total amount of steel rebar required to prevent progressive collapse at midspan of a continuous beam section where a column loss has occurred. The research results provide insight into the minimum amount of reinforcing steel actually needed to achieve a demand to capacity ratio of approximately 1.0 and prevent collapse in the event of a single column loss. Several relationships are developed between span lengths, distributed loading, column loading, and steel required. The maximum allowable loads are calculated to show how to best prevent progressive collapse. The results are obtained using different models where combinations of pinned end and fixed end support configurations are used along with analysis of nominal moment strength of the beam versus the plastic moment strength of the beam. Ultimately, tables and graphs are developed that could eventually be used in design codes where there are currently very limited or no specific rules or guidelines directed towards prevention of progressive collapse.
