[摘要] 讨论了PERFORM-3D在结构弹塑性分析建模中的问题，以重庆市某超限高层建筑为例，建立了结构动力弹塑性时程分析模型，分析了大震下结构的变形、受力、耗能特征以及结构构件的塑性变形特征，对结构的整体反应和构件损伤情况进行了评估。研究表明：PERFORM-3D在超高层建筑结构弹塑性分析中具有较好的适用性。算例结构具有较好的抗震性能，能够满足预定的抗震性能目标。

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.
