［摘要］采用ABAQUS软件对试验中的3个钢筋混凝土柱-钢梁(RCS)组合节点进行三维非线性有限元分析，比较分析模拟、试验及改进后恢复力模型之间的差异。结合试验结果，分析轴压比、混凝土强度和节点构造措施对RCS组合节点滞回曲线、骨架曲线、承载力、变形能力、耗能特性、刚度退化和强度退化等因素的影响，为RCS组合框架抗震研究提供参考。

Abstract:The nonlinear three-dimensional finite element analysis of three reinforced concrete column and steel beam(RCS) composite joints with different details conducted  was performed by the  software ABAQUS and the analytical results were compared with the experimental results and proposed hysteresis model. Combined with experimental results, the axial compression ratio, concrete strength and joint details affecting the restoring force performance of the RCS composite joints including the hysteretic curve, skeleton curve, capacity, ductility, stiffness degradation and strength degradation of specimens were analyzed, which can provide references for the seismic analysis of RCS composite  structures.

Keywords:reinforced concrete column and steel beam; composite joint; restoring force feature; seismic behavior
