| Abstract: | The philosophy and methodology of performance-based seismic design has been an extensive topic discussed by structural engineering expert at home and abroad.Incremental dynamic analysis(IDA) is a parametric analysis method to estimate more complete structural performance under seismic loads.The basic contents and feasible measure of incremental dynamic analysis are introduced.The 6–story steel frame is systematically analyzed,and the IDA curves are obtained. |
