ICCBT 2008 - C - (06) – pp69-80 ICCBT2008 Nonlinear Static Pushover Analysis in Earthquake Engineering: State of Development M. Seifi*, Universiti Putra Malaysia, MALAYSIA J.

Yazdan Panah, Universiti Putra Malaysia, MALAYSIA ABSTRACT Owing to the simplicity of nonlinear static pushover (NSP) analysis compared to nonlinear dynamic time-history analysis, currently proliferation in usage of NSP method is observed among society of civil engineers. Conceptually, NSP method relies on pushing the structure with incremental static lateral load by considering material inelasticity and geometric nonlinearity. In this study, initially the fundamental concept of NSP method was declared. Subsequently, the state of development of pushover analysis from pilot studies to the ones that found its way to FEMA-356, as the most prevalent practical code, to the state-of-art among novel proposed methods was presented and more than 10 types of innovative methods was investigated. The results criticized the pros and cons of each method. Eventually, the superior method in aspect of accuracy in accompany with simplicity of computational procedure was unveiled.
