摘要
简要阐明了钢材和混凝土材料的本构关系及结构动力弹塑性分析方法.基于ABAQUS有限元分析软件,对若干典型大跨空间结构进行地震大震作用下的结构动力弹塑性分析.计算分析显示,基于本方法的计算结果可靠、准确,可真实地获得结构逐步损伤和损坏的历程,揭示结构的薄弱环节和可能的破坏形式.
The nonlinear constitutive model of structural steel and coneIete materials as well as the dynamic elasto-plastic analysis method were clarified. The dynamic elasto-plastic analysis for some practical long- span spatial steel structures under strong seismic wave records are carried out by using finite element analysis software ABAQUS. It is indicated that the results based on the present method was accurate and reliable. The gradually damage course, the weak links and possible failure modes of structural system can be revealed.
