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
