英文摘要	One cast-in-place specimen and two prefabricated specimens were constructed and tested under cyclic reversed loading to study the seismic behavior of the prefabricated concrete beam-column joints, such as its failure modes, hysteretic performance, displacement ductility, stiffness degradation and energy dissipation capacity, and the effects of axial compression ratio on seismic behavior for the joint were also studied. A finite element model was established by ABAQUS to expand the range of influential factors, and the influence of various factors on the seismic behavior of the joint was further analyzed, including the ratio of longitudinal reinforcement, post-cast concrete strength and yield capacity of steel plate. The results show that the prefabricated specimen performs much better than the cast-in place specimen in terms of the bearing capacity, stiffness and energy dissipation capacity except of the similar deformation performance. As the axial compression ratio increases, the bearing capacity, stiffness and energy dissipation capacity of the joint obviously increase, but the ductility decreases. The seismic behavior of joints can be improved by increasing the ratio of longitudinal reinforcement and the post-cast concrete strength. The plastic hinge can be transferred to the outside of the column by changing the yield capacity of steel plate, and the steel plate can be used to dissipate energy when the yield capacity of steel plate is approximately equal to the that of longitudinal reinforcements. © 2021, Editorial Office of Journal of Building Structures.
