摘　　要：利用Ansys软件对钢梁-内埋型钢柱剪力墙组合节点的抗剪性能进行了数值模拟,针对组合节点核心区设置和不设置加劲肋两种情况,对试件的滞回响应和耗能特性进行分析.结果表明加劲肋的存在可以提高节点的承载能力,但会使节点的延性出现明显的削弱.同时,加劲肋可以提高节点的刚度,但是并不能改变节点刚度的退化趋势.Numerical simulation was made on girder-buried steel pile shear wall by means of the shearing performance of composite joints in the steel the Ansys software. In view of the conditions of composire joint kern with and without stiffening ribs, this paper analysed the hysteresis responses and energyconsuming properties of the test specimens. The results show that the existence of stiffening ribs can improve the bearing capacities of joints, but may lead to obvious debilitation of their ductility. Meanwhile, stiffening ribs can increase the rigidity of joints, but can＇t alter its degenerate tendency.
