摘要: 采用三维非线性有限元分析方法,讨论了钢结构半刚性梁柱节点连接的杠杆力分布及杠杆效应对节点连接受力性能的影响。按塑性设计理论给出了节点连接杠杆力的最大值,提出了保证节点工作性能安全、可靠的计算方法,以利于工程设计。Abstract: A 3D nonlinear finite element method is used to analyze the distribution of prying forces of semi-rigid beam-column connections of a steel structure and the effect of the prying forces on the forced performance of the connections. The maximum of the prying force is deduced according to plastic design theory. And the corresponding computational method ensuring the safety and credibility of such connections is advanced.
