摘　　要：比较了6个常用动力弹塑性分析软件的计算模型和结果,并分析比较了弹塑性计算结果与拟静力试验结果的差异,塑性铰模型和纤维束模型在模拟梁、柱构件上的差异,以及纤维束模型、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。工程算例表明,各软件计算的框架结构变形和动力特性基本一致,但剪力墙结构存在一定差异。最后给出4点建议供选择弹塑性时程分析软件时参考。The computing models and results of 6 commonly used dynamic elastic-plastic analysis softwares were compared.The differences between the elastic-plastic calculation results and the static test results,the differences between the plastic hinge model and the fiber model for beams and slabs,and the differences among the fiber model,the shell element model and the elastic-plastic damage model for shear-walls were analyzed.The calculation results of buildings show that the deformation and bearing capacity of the frame structures by different softwares are almost same,but there are some differences for shear-wall structures.Finally,4 important points summed up for choosing an appropriate elastic-plastic software were given.
