摘　　要：通过拟静力试验以及有限元ALGOR程序,对钢框架T型钢连接节点进行了低周反复荷载作用下试验研究和非线性有限元分析,研究了T型钢连接节点的破坏形式、受力性能。分析结果表明:T型钢连接节点具有较好的延性,翼缘刚度的不同对延性影响较大;T型钢连接节点的滞回曲线稳定饱满,具有较为理想的抗震耗能作用;翼缘的厚度对T型钢连接强度的影响较大。By quasi-static test and finite element ALGOR program, it has been done that the experimental research under low-cycle repeating horizontal load, non-linear finite element analysis. And the damage form and mechanical performance of T-joint have been studied. The results of analysis indicate that T-joint has better ductility, the difference of the rigidity of flange has great influence on ductility; the shapes of P - △ curve are stable and full, T-joint has perfect seismic performance ; the thickness of flange has great influence on the strength of T-joint.
