摘　　要：为探究影响方钢管柱-H型钢梁外加强环式不等高梁节点域力学性能的参数,以梁高比、柱宽厚比、轴压比、梁翼缘宽厚比、梁柱宽厚比和节点域高宽比为分析参数,采用有限元分析软件ABAQUS,在对比已有试验结果验证有限元模型可靠性的前提下,对节点模型进行了单向位移加载下非线性数值模拟分析。研究结果表明:柱宽厚比对不等高梁节点域剪切初始刚度有明显影响;梁高比、柱宽厚比和梁翼缘宽厚比对节点域的变形能力有一定影响;梁高比和柱宽厚比对不等高梁节点域的剪切承载力影响较大。In order to investigate the parameters of the mechanical properties of the unequal-depth-beam-to-column connection panel zone with external-diaphragm, beam-depth ratio, column width thickness ratio, axial compression ratio, beam flange width thickness ratio, width to thickness ratio and aspect ratio of connection were employed as investigation parameters. Based on the finite element analysis software ABAQUS, the numerical simulation of the joint model under uniaxial loading was carried out under the premise that the reliability of the finite element analysis was verified. The results showed that the parameters of column width thickness ratio had a significant influence on the initial shear stiffness of the panel zone. The parameters of width to thickness ratio, beam flange width thickness ratio and beam depths ratio had a certain influence on the deformation ability of the panel zone. The parameters of width to thickness ratio and beam depths ratio had a great influence on the shear strength capacity of the panel zone.
