比较了常用弹塑性分析软件的推覆分析功能,分析了塑性铰模型和纤维束模型在模拟梁柱构件上的差异,纤维束模型、壳元损伤模型和弹塑性墙元模型在模拟剪力墙构件上的差异。通过四个算例对比了五个软件的计算结果,发现各软件计算的结构承载能力存在较大差异。分析了各软件计算结果不同的原因,供设计人员在进行结构推覆分析时参考。
Compared with the pusher analysis function of commonly used elasto-plastic analysis software, the differences between the plastic hinge model and the fiber bundle model in the simulation of beam and column components were analyzed. The fiber bundle model, the shell damage model and the elastoplastic wall element model were compared in simulation shear wall Differences in components. The results of five softwares are compared by four examples. It is found that there is a big difference between the structural carrying capacity calculated by each software. The reasons for the different calculation results of each software are analyzed for designers to refer to when making structural pushover analysis.
