【 摘 要 】

Shear wall systems as horizontal load resisting system are used widely in high-risen building. An innovative shear wall, named Precast Concrete (PC) composite shear wall with confined boundary elements, is proposed in this paper. The new-style structural wall is composed of PC panels, in-filled concrete and confined boundary members. Three full-scale specimens were subjected to cyclic lateral load under axial load. These structural characteristics were investigated and analysed including bearing capacity, hysteretic loops, skeleton curves, ductility, and energy dissipation under cyclic load. The specimens exhibited good ductility and underwent stable seismic behavior. Specially, the precast shear wall with joint motor show sufficient ductility, deformation capacity, stiffness and energy dissipation. The specimens experience the failure in the sequence of concrete crushing and the propagation fractures at the boundary of the wall. The experimental results indicate that the confined boundary elements have a great remarkable effect on the precast shear wall.
