［摘要］以7度區(qū)某復雜高層SRC框架-核心筒結(jié)構(gòu)為例，利用軟件PERFORM-3D和MIDAS Building對結(jié)構(gòu)進行非線性動力反應分析，從大震下結(jié)構(gòu)的最大彈塑性變形及結(jié)構(gòu)損傷狀態(tài)方面對兩種軟件分析結(jié)果進行了對比，并從軟件前后處理、材料模型、單元模型等方面對兩種軟件的結(jié)構(gòu)非線性分析功能模塊進行了比較探討。結(jié)果表明：在大震下兩種軟件計算結(jié)構(gòu)彈塑性變形結(jié)果和塑性損傷分布總體較為接近，但在配筋條件、材料單元模型、強度指標等方面存在差異。

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
