In order to study the seismic performance of steel core plate and concrete composite shear walls with PBL shear connectors,the cyclic loading tests of four steel core plate and concrete composite shear walls and one steel and reinforced concrete composite shear wall were carried out.The failure process of steel core plate and concrete composite shear walls with PBL shear connectors under horizontal cyclic loading was observed.The hysteresis performance,deformation capacity,bearing capacity,energy dissipation and degradation of stiffness and strength of the shear wall were analyzed.The results show that the failure mode of steel core plate and concrete composite shear walls is bending failure and the hysteresis curves are relatively full.The shear walls with steel core plate have good bearing capacity,ductility and energy dissipation.The adhesive property between steel core plate and concrete can be guaranteed by configurations of PBL shear connectors.The horizontal arrangement of PBL shear connectors can cause the horizontal seams of shear walls along PBL connectors,which have an impact on bearing capacity of shear walls.Therefore,the vertical arrangement of PBL shear connectors is sugges-ted.
