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。
Taking the complex SRC frame-core tube structure in a 7-degree zone as an example, the software PERFORM-3D and MIDAS Building are used to analyze the nonlinear dynamic response of the structure. From the view of the maximum elastoplastic deformation and structural damage of the structure, The results of software analysis are compared and the functional nonlinear modules of two kinds of software are compared and discussed from the aspect of software preprocessing, material model and unit model. The results show that the elastic-plastic deformation results and plastic damage distribution of the two kinds of software are generally close under large earthquake, but there are differences in reinforcement conditions, material unit model and strength index.
