摘　　要：为了解钢框架节点抗震性能,设计并制作了1个普通型和1个对称双肋板加强型钢框架梁柱节点试件,并通过低周往复加载试验研究其滞回性能,对比分析了这两种钢框架梁柱节点的滞回曲线、骨架曲线、延性、耗能能力以及损伤退化等指标.基于试验结果,运用ABAQUS有限元软件建立了普通型和对称双肋板加强型钢框架梁柱节点三维有限元分析模型,并对低周往复荷载下这两类节点进行数值分析.结果表明:双肋板加强型节点相较于普通型节点而言,承载能力高,塑性性能好,建议在实际工程运用中优先使用.One conventional and one double-ribbed reinforced beam-column connection specimens of steel frame are designed.The hysteretic performance is studied by low-cycle loading,and the hysteretic curves,skeleton curves,ductility,energy dissipation capacity and damage degradation of these two beam-column connections of steel frame are compared and analyzed.Based on the experimental results,a three-dimensional finite element analytical model of the conventional and double-ribbed reinforced beam-column connection of steel frame is established and analyzed under low-cycle loading through ABAQUS.The results show that the double-ribbed reinforced beam-column connections have higher bearing capacity and plastic performance than the conventional beam-column connections,which can be used in practice.
