摘　　要：采用通用有限元程序ANSYS,对T型钢连接节点进行了非线性分析,讨论了连接节点在各级荷载下的应力分布及发展情况,分析了节点各组成要素对节点受力性能的影响.分析结果表明:T型钢连接节点属于半刚性连接节点,具有良好的延性;柱翼缘厚度、T型钢翼缘厚度和梁截面高度对节点的极限承载力和初始刚度均有很大影响;为T型钢半刚性连接在工程上的应用,提出了相关建议.With the finite element program ANSYS, the nonlinear analysis to this con- nection is made. The stress distribution of T-stub, beam and column under all levels of loads are discussed,and the effects of its components on its behaviors are analyzed. The results show that this kind of T-stub connections is semi-rigid one. The thickness of flange of the column and the T-stub and the beam height greatly influence the behaviors of the connections, and some relevant suggestions for T-stub semi-rigid connections in engineering application are raised.
