Practical 3D nonlinear static pushover analysis using SAP2000

This article presents the steps used in performing a pushover analysis of asimple three-dimensional building. SAP2000, a state-of-the-art, generalpurpose, three-dimensional structural analysis program, is used as a tool for performing the pushover. The SAP2000 static pushover analysiscapabilities, which are fully integrated into the program, allow quick and easy implementation of the pushover procedures prescribed in the ATC-40 and FEMA-273 documents for both two and three-dimensional buildings.
