Structural Analysis and Design to Prevent Disproportionate Collapse


The first time I was involved with disproportionate collapse prevention design was in 2007. That was the first time I encountered design guidance for progressive collapse, such as those from the General Services Administration (GSA) and the Department of Defense (DOD). One of the difficulties I noticed at that time was that there was no software available to accurately perform progressive analysis for tall buildings or other complex structures, such as long-span space structures. Therefore, working together with my colleagues and using the general-purpose program Abaqus

I developed the progressive collapse analysis method based on the alternative path method. This method was found to be effective and has since been used for several other projects.After that, I moved into academia and continued my research in progressive collapse analysis of different types of structures, such as tall buildings, bridges, and space structures, under extreme loading, such as fire and blast. I accumulated extensive experience in the area of structural design to prevent disproportionate collapse.

In the meantime, I also noticed that most design engineers lack knowledge of the theories and modelling techniques in progressive collapse analysis and design of complex structures. For students, there is also a large knowledge gap, as there are few textbooks available that cover the design and analysis of a structure to prevent disproportionate collapse.The motivation for this book was to provide engineers with an understanding of the disproportionate collapse problems for different types of structures under different loading regimes, effective methods to model and analyze these types of structures using conventional commercial software such as Abaqus, ETABS, and
SAP2000, and the theories and design principles that underpin the relevant analysis. Another objective of this book is to provide civil engineer students with detailed knowledge in design and progressive collapse analysis of complex structures. Therefore, this book has been written not only to serve college and university students, but also as a reference book for practicing engineers
