摘　　要：该文分析对象为圆管柱钢框架节点,节点加强方式为外环板加强方式,钢框架节点为中柱节点,节点两端钢梁梁高不同。分析手段采用数值分析法,分析软件为有限元分析软件ABAQUS,变量参数为:轴压比、管壁厚、外环板厚度、梁高差值。通过建立3组共9个有限元分析模型,进行节点的受力模拟试验,并通过试验结果数据整理、总结,得出3个变量参数对钢框架节点力学性能的影响规律。The analysis object of this paper is the steel frame joint of round pipe column.The node reinforcement method is the outer ring plate reinforcement,the steel frame node is the middle column node,and the steel beam height at both ends of the node is different.Numerical analysis method is adopted,and the analysis software is finite element analysis software ABAQUS.The variable parameters include axial compression ratio,pipe wall thickness,outer ring plate thickness,and beam height difference.Through the establishment of 3 groups of 9 finite element analysis models,the experiment simulation was carried out.By sorting and summarizing the data of the experiment results,the influence of three variable parameters on the mechanical properties of the steel frame joints is obtained.
