PUSHOVER ANALYSIS : Why , How, When, and When Not to Use It

The static pushover analysis is becomea popular method of predicting seismic force and deformation demands for the purpose of performance evaluation of existing and new structures. If applied thoughtfully and with good judgment, it will provide much useful information that cannot be obtained from elastic static or dynamic analysis procedures. However, the method is based on many assumntions that may provide misleading results in some case. thus, the pushover need to be viewed as an engineering tool with much potential, but with pitfalls that have to be recognized in order to avoid gross misinterpretations. This paper points out some of these pitfals, but its main focus is a general discussion on the pushover's advantages (why to use it ), background and implementation (how to use it), and applications(when to use it).
