| Abstract: | Push-over analysis is an important method for performance-based seismic design.Based on the principles,this paper reviews the principles of Push-over analysis,presents the analysis procedures of Push-over analysis which is adaptable to China Code for seismic design.By means of SAP2000,a case of Push-over analysis is presented.With the results which include shear force-displacement,distribution of the plastic hinges,the seismic performance of the structure is evaluated.It is proved that Push-over analysis is an effective method for structural analysis under the maximum earthquake. |
