The influence of the joint zone thickness on normal beam-column joints ductility performance was discussed. ABAQUS-a large-scale finite element analyzing software was applied to perform simulation tests on NBJ(Normal Beam Joint)under low-cycle reciprocating load. Based on the analysis of hysteresis curve and ductility factor, the influence of the thickness of the joint zone on normal beam-column joints ductility performance was studied. After the comparative analysis, the conclusion was drawn that the thinner the joint zone is, the stronger the plastic deformation ability is, and the best ductility performance is.%探讨了节点域厚度对普通梁柱节点延性性能的影响。利用大型有限元分析软件 ABAQUS 对普通型梁节点(normal beam joint,NBJ)进行低周往复加载下的模拟试验。通过对滞回曲线及延性系数的分析,讨论节点域厚度对其节点延性性能的影响。经过对比分析得出节点域越薄,其节点的塑性变形能力越强,延性性能越好的结论。
