Synopsis
"Earthquakes don't kill people, buildings do." That has long been the clich but true axiom of all approaches to mitigating the dangers of earthquakes to people. And in that light, structural engineers have derived many analytic approaches to understanding how buildings behave when enduring the different kinds of shock waves generated by earthquakes and how to design buildings to resist being destroyed by those shock waves. One of the more innovative approaches has been the "endurance time method." This is a time-based, dynamic structural analysis computational method that can give good approximations of complex structural behavior under earthquake forces, and do so with more simplified analysis. It is a relatively new analytical tool, having only been conceptually developed in 2004 and actually applied beginning in 2007. It is proving itself to be highly useful, and this book covers the basic principles of the method, and the critical nature of excitation functions. The second volume explains practical, proven applications in designing earthquake-resistant structures, and analysis of structural response to actual seismic events. It offers applications of the method to a number of seismic engineering problems, including multicomponent analysis and value-based seismic design.
Synopsis
A new approach to seismic assessment of structures called endurance time method (ETM) is developed. ETM is a dynamic analysis procedure in which intensifying dynamic excitations are used as the loading function. ETM provides many unique benefits in seismic assessment and design of structures and is a response history-based procedure. ETM considerably reduces the computational effort needed in typical response history analyses. Conceptual simplicity makes ETM a great tool for preliminary response history analysis of almost any dynamic structural system. Most important areas of application of ETM are in the fields of seismic design optimization, value-based seismic design, and experimental studies. This book is aimed to serve as a coherent source of information for students, engineers, and researchers who want to familiarize themselves with the concepts and put the concepts into practice.
