基于2个新型柱外传力式节点和2个传统节点的试验结果,采用大型有限元软件ANSYS对节点在单调荷载作用下的受力性能进行有限元分析,研究了两类节点的极限荷载、应力分布、应力发展规律、破坏形态。有限元计算得到的荷载-位移曲线和局部破坏形态与试验结果吻合较好。研究结果表明,增设传力板使得节点应力得到改善,从而避免梁根部应力发展导致梁柱连接处焊缝过早地发生脆性破坏,而且增设传力板使得节点承载力得到提高。 Based on the test results of two new type of external force transmitting nodes and two traditional nodes, the finite element analysis software FEA ANSYS is used to analyze the force behavior of nodes under monotonic loading. The ultimate load and stress of two kinds of nodes Distribution, the law of stress development, damage morphology. The load-displacement curve and local failure mode calculated by finite element method agree well with the experimental results. The results show that the additional stress plate to improve the node stress, so as to avoid the stress at the root of the beam leading to premature brittle failure of the weld at the beam-column connection, and increase the load-carrying capacity of the node.
