探讨了节点域厚度对梁端翼缘削弱型节承载力的影响，利用大型有限元分析软件 ABAQUS 作为工具，对梁削弱型节点进行低周往复加载下的模拟试验。通过对加载现象、应力云图的对比分析，研究讨论了节点域厚度对梁端翼缘削弱型节点承载力的影响。经过分析得出在一定范围内节点域越厚节点的极限承载力越大；柱的局部屈曲能导致节点丧失15%~25%的承载力，梁的整体侧移能导致节点丧失50%的承载力。

The influence of the thickness upon the joint zone on the bearing capacity of the joint with the reduced beam-end flange was discussed. ABAQUS-a large-scale finite element analyzing software was applied to perform simulation tests on RBJ(Reduced Beam Joint) under low-cycle reciprocating load. Based on the comparative analyses of loading phenomenon and stress nephogram, the influence of the thickness of the joint zone on the bearing capacity of the reduced joint of the beam end flange was researched. After the analysis, in a certain range domain, the thicker the joint zone is, the larger the ultimate bearing capacity is, the local buckling of the column can result in 15%-25%lost of the bearing capacity of the joint, the overall lateral of the beam can result in 50%loss of the bearing capacity of the joint.
