Progressive Collapse Analysis of Concrete-filled Steel Tubular Structures looks at quantitative design, namely direct design and how catenary action plays a critical role in resisting progressive collapse. After the failure of a structural column due to abnormal loads, such as explosion, fire, or vehicle strikes, the loads acting on the damaged column tend to be redistributed through the beams connected to the damaged column. Catenary action would form in the beams and beam-column joints to resist vertical loads. The failure of beam-column joints would prevent the forming of catenary action, which would initiate local collapse and even the progressive collapse of structures. Even though a few studies had been conducted on the progressive collapse resistance of the RC and steel structures with brace members, the study on the effect of tensile steel brace on the collapse resistance of composite frame with CFST (Concrete-filled Steel Tubular Structures) columns has been rarely reported/examined.

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

In this research, experimental and analytical analysis of the progressive collapse potential of existing building were evaluated. The progressive collapse design guidelines typically recommend simplified analysis procedures involving instantaneous removal of specified critical columns in a building. The design guidelines were developed based on a majority of laboratory and numerical research. In this research, experimental data from the column removal from multiple structures is used to calibrate and validate numerical analysis methods. The current research involves one steel frame structure and three reinforced concrete structures. This data will be in addition to previous research conducted under a continuing program at The Ohio State University. The overall objective of this research is to evaluate the appropriateness of existing progressive collapse analysis and design requirements.

Geopolymer Concrete Structures with Steel and FRP Reinforcements: Analysis and Design focuses on structural behavior, including the aspects of compression, bending strength and combined action of GPC members, with the book's content based on published studies over the last two decades. Geopolymer concrete (GPC) structural members reinforced with FRP reinforcement have some advantages in resisting forces compared to conventional concrete or steel tubular members. Among the most important are the high strength and bending stiffness, fire and impact performance and favorable, construction ability and durability. To this end, there are no significant applications of these new structural elements worldwide, partly due to the lack of the understanding of their behavior and insufficient design provisions in different design manuals. This book, therefore, seeks to highlight their characteristics and future potential. Provides comprehensive, up-to-date advances on Geopolymer Concrete (GPC) reinforced with steel and FRP bars and stirrups construction with a summary of over 100 papers published in the last decade Compares the behavior and failure modes between Geopolymer Concrete (GPC) structures and Ordinary Portland Concrete (OPC) structures Explains important concepts such as bond, confinement, fracture of stirrups and buckling of FRP bars Includes an in-depth analysis of ultimate strength of GPC and OPC, considering governing failure modes Presents design examples following international standards, including North America ACI 440.1R-15, Canadian CAN/CSA S806, and Australian such as AS 3600

The interest of Structural engineers is increasing to prevent the progressive collapse of the building. After the collapse of World Trade Center (WTC) Tower many government and private authorities worked on developing design guidelines for progressive collapse resistant structures. Among all the guidelines the U.S. General Service Administration (GSA) and Department of Defense (DoD) is most widely used by structural engineers. Historical background, mechanism, causes and types of progressive collapse is discussed in this book. This book also represents progressive collapse analysis of 4-storey and 10-storey Asymmetrical reinforced concrete (RC) building considering GSA and DoD guidelines. Linear static and dynamic as well as nonlinear static and dynamic analysis is carried out using Alternate Path Method (APM). APM is threat independent method in which critical columns from ground floor and intermediate floor are removed and demand-capacity ratio (DCR) is found out for beams and columns. From the values of DCR potential for progressive collapse is analysed. Different alternatives are explored to mitigate the potential of progressive collapse of buildings.

Recent tragedies involving the collapse of several large and prominent buildings have brought international attention to the subject of progressive collapse, and the field of structural engineering is actively investigating ways to better protect structures from such catastrophic failures. One focus of these investigations is the behavior and performance of shear tab connections in steel structures during progressive collapse events. The shear tab, a simple connection, is typically modeled as a perfect pin in standard design, but in progressive collapse analysis, a much more accurate model of its true behavior and limits is required. This report documents the development of a simple yet accurate shear tab model and its use in understanding the behavior and limits of shear tab connections in column removal scenarios. Particular attention is paid to the connections' axial force limit state, an aspect of behavior that is typically unimportant in standard design.
