摘　　要：为进一步研究斜柱式转换结构的抗震性能,应用非线性有限元软件Sap2000,分别研究一榀梁式框支剪力墙模型和一榀斜柱式框支剪力墙模型,进行静力弹塑性(Push-over)分析。并将两种模型的力学特点、传导途径、初始刚度、延性比、塑性铰的出现次序等进行对比研究。结果表明相对于梁式转换结构,斜柱式转换结构的传导途径简洁,初始刚度更大,延性更好,塑性铰的出现次序更有利于实现强节点,是一种有效的抗震结构体系。In order to study the seismic performance of inclined column transfer structure,a beam type frame supported shear wall model and an inclined column type frame supported shear wall model are studied respectively by using nonlinear finite element software Sap2000,in which the static elastoplastic(Push over)analysis is carried out.The mechanical characteristics,conduction path,initial stiffness,ductility ratio,and the occurrence order of plastic hinges of the two models are compared.The results show that compared with the beam type transfer structure,the inclined column type transfer structure has simple conduction path,greater initial stiffness,better ductility,and the occurrence order of plastic hinges is more conducive to achieving strong joints,which is an effective seismic structural system.
