Abstract:The theoretical problems in the static elastoplastic analysis (pushover analysis) are proved and discussed, which include the formation of equivalent single degreeoffreedom (SDOF) system,the creation of equivalent viscous damping,and the solving of the performance points. The merit and the limitation of ETABS and PUSH program are also pointed out, the method of equivalent columns taking the place of walls in ETABS is made further investigated on the basis of document 2.
Keywords:static elastoplastic; equivalent viscous damping;equivalent column; pushover analysis
