［摘要］以7度区某复杂高层SRC框架-核心筒结构为例，利用软件PERFORM-3D和MIDAS Building对结构进行非线性动力反应分析，从大震下结构的最大弹塑性变形及结构损伤状态方面对两种软件分析结果进行了对比，并从软件前后处理、材料模型、单元模型等方面对两种软件的结构非线性分析功能模块进行了比较探讨。结果表明：在大震下两种软件计算结构弹塑性变形结果和塑性损伤分布总体较为接近，但在配筋条件、材料单元模型、强度指标等方面存在差异。

Abstract:Based on a complex high-rise SRC frame-core tube structure of 7 degrees district as an example, the nonlinear seismic response was studied with two different softwares PERFORM-3D and MIDAS Building. The differences in analysis results of two softwares were compared from the relativity of the structure under maximum elasto-plastic deformation and structure damage status, and the nonlinear analysis function modules including the pre-post processing, material model, unit model of two softwares were discussed. The results show that under rare earthquake, the elastic-plastic deformation and plastic damage distribution of the structure calculated by the two softwares are close to each other, but there are different in reinforcement condition, material element model, strength index.

Keywords:complex shape; SRC frame-core tube structure; PERFORM-3D; MIDAS Building; nonlinear seismic response analysis
