| 摘 要： | 采用ANSYS有限元软件对T型钢梁柱节点进行三维实体建模，并在此基础上利用非线性有限元方法研究不同节点在低周往复荷载作用下的滞回性能。结果表明：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性能。T型钢翼缘厚度、是否设置加劲肋和螺栓竖向排列方式对节点抗震性能影响较大；柱腹板厚度、梁翼缘和腹板厚度对抗震性能影响较小，T型钢梁柱节点属于半刚性节点。

| Abstract: | The hysteretic behavior of T-stub beam-column joint under cyclic load is studied by using the method of three-dimensional modeling of solid structures.The results show that the shapes of P-Δ curve are stable and full.T-joint has perfect seismic performance;the thickness of flange of the T-stub,stiffening rib and the vertical array distribution of bolts greatly influence the seismic performance of the joints;the thickness of web of the column,the thickness of flange and web of beam have less influence,T-stub beam-column joint is semi-rigid joint. |

| Keywords: | T-stub connection beam-column joint cyclic load anti-seismic capacity nonlinear finite element analysis |
