| 摘 要： | 应用有限元软件ABAQUS建立了7组圆钢管柱H型钢梁外加强环式节点分析模型，建立了包含梁翼缘宽度和厚度、梁腹板厚度和高度、圆钢管柱壁厚、外环板宽度、轴压比等参数的节点承载力和刚度评价公式。利用OpenSees软件模拟一组试验试件，试验试件中的节点参数选用已有的承载力和刚度评价公式，通过分析结果与试验结果的对比，验证了节点评价公式的正确性以及节点建模的可行性，该方法可以应用到钢框架节点设计研究中。

| Abstract: | Seven of circular hollow section column and H-shaped beams analysis models were established by ABAQUS. The main parameters include the beam flange thickness and width, the beam web thickness and height, the column thickness, the external diaphragm width and the thickness. The influence of the main parameters on the bearing capacity and the stiffness had been investigated. OpenSees program also been used in this paper to compare with the test results using the evaluating formula come from the finite element analysis results. |
