Effects of Strength and Stiffness Degradation on Seismic Response

Cover photo for the document: Effects of Strength and Stiffness Degradation on Seismic Response
This document is a follow-on publication to Improvement of Nonlinear Static Seismic Analysis Procedures (FEMA 440). It provides information that will improve nonlinear analysis for cyclic response, considering cyclic and in-cycle degradation of strength and stiffness. Recent work has demonstrated that it is important to be able to differentiate between cyclic and in-cycle degradation in order to more accurately model degrading behavior, while current practice only recognizes cyclic degradation, or does not distinguish between the two. The material contained within this publication is expected to improve nonlinear modeling of structural systems, and ultimately make the seismic retrofit of existing hazardous buildings more cost-effective.
