摘　　要：为了研究顶底角钢连接半刚性梁柱钢节点的滞回性能,利用ANSYS软件对该节点进行了循环荷载作用下的非线性有限元分析。分析考虑了几何、材料和接触非线性,获得了节点的应力分布、变形情况、以及连接的M-θ滞回曲线,并与试验结果进行了对比。研究结果表明:顶底角钢连接节点具有良好的延性和耗能能力;ANSYS可用于模拟角钢连接半刚性节点的受力性能。In order to study the hysteretic behavior of the semi-rigid steel joints with top and seat angle connection, nonlinear finite element analyses under cyclic loading are carried out for the joints using ANSYS software. Geomet- ric nonlinearity, material nonlinearity and contact nonlinearity are considered in analyses. The stress distribution, plastic deformation and hysteretic curve of the connection are acquired from the analyses. The analytical results, which are compared with the test results, show that top and seat angle connection exhibits good ductility and good energy dissipation capacity. It also shows that ANSYS can be used to simulate the performance of the semi - rigid joints with angle connection.
