Abstract:
In order to evaluate the effect of reinforced concrete(RC)slab on seismic behavior of the composite joint, five scale 1/2 composite joint specimens were designed considering the slab effect and the joint construction, which were tested under the combined action of vertical axial force and horizontal low-cycle reversal load at column end. Meanwhile, the nonlinear finite element analysis(FEA)model of the composite joint was established considering the confinement effect, damage and stiffness recovery characteristics of concrete filled in steel tubes. Based on the validated FEA model, the influence law of the design parameters on the mechanical behavior and initial stiffness of composite joints was investigated. The results show that slab action is beneficial to improve the bearing capacity and initial stiffness of composite joints. However, the failure mode of composite joints sometimes can change from beam failure to column failure. Therefore, the slab effect cannot be ignored in the study of composite joints. The flexural capacity and initial stiffness of composite joints are enhanced with increasing of column axial compression ratio, floor thickness, column steel ratio, and beam-column linear stiffness ratio in a certain range. The beam-column linear stiffness ratio is the crucial parameter which can influence the failure mode of composite joints. The beam-column linear stiffness ratio of the composite joints with slab is recommended to be about 1.0 to avoid column failure, and the mechanical performance of the composite joints is also better.
