| Abstract: | This paper reviews the basic principles and methods of the static elasto-plastic analysis (pushover analysis) in FEMA273/274 and in ATC-40. Its main calculation procedures are summarized and a case study is presented for the frame-shearwall structure designed according to China Code for Seismic Design by means of ETABS. It has been proved that pushover analysis is a effective method of structural elastoplastic analysis under the maximum earthquake action. |
