| Abstract: | Pushover analysis,which is widely recognized and applied at home and abroad,is an inelastic static analysis method based on displacements.In this paper,the principle and application procedure of the method in SAP2000N are firstly explained,then an eccentric braced steel frame is analyzed.According to the Pushover curve,the approach and trial calculation of the performance point is completed.In addition,it is shown that the Pushover analysis can estimate the yield mechanism,the weak parts and the performance... |
