摘　　要：对 4种构造形式的钢框架梁柱节点进行了非线性有限元分析 ,求得了其应力分布、塑性区分布及极限承载力 ,并对节点的力学性能进行了分析比较 ,结果与试验结果吻合较好。基于理论分析和试验研究 。By using the nonlinear FEM the authors analyzed four types of connections with different details.The stress distribution,the development process of plastic zones with the raising of applied load and the bearing capacity of the connections are calculated.And the mechanical behaviors of the different connections are analyzed and compared.The comparison between the results of the analysis and those of the experiment is satisfactory.The connection with modified detail is presented based on the results of the analysis and experiment.
