( School of Civil Engineering, Chongqing University, Chongqing 400045, China)Abstract: Some problems in establishing elastic-plastic analysis modal based on PERFORM-3D software were discussed. Elastic-plastic time-history is performed ona super-high building in Chongqing under the scarce earthquake. Deform, stress, dissipation energy and element plastic deform feature were analyzed. Also, overall response and element damage were evaluated. The results show that PERFORM-3D software is suitable in elastic-plastic time-history for super-high buildings. This structure has a well seismic performance and can also achieve the predestinate performance goal.
Keywords: super-lugh building; elastic-plastic time lustory analysis; PERFORM-3D; seismic performance evaluation
