Abstract: The static elasto-plastic (Pushover) analysis is an important method for evaluate structure of in existence and design new structure that base on performance, and which has been recommended by the new national Code of Seismic Design of Buildings. A concise introduction to the principle and procedures of Pushover was presented, and a structure design example that based on MIDAS was presented and analyzed, further give the advice for designer.
Keywords: static elasto-plastic analysis; Pushover; connect twin-towers
