摘　　要：为提高双层钢板混凝土组合剪力墙的施工效率,提出了设置竖向通缝、水平缝通过螺栓连接的装配式双层钢板-混凝土组合剪力墙,并对6个缩尺比为1∶2的组合剪力墙进行了拟静力试验,得到其破坏形态、滞回性能、应变、刚度和承载力退化、耗能能力等试验结果,分析设置竖向通缝、不同形式水平缝螺栓连接等构造对组合剪力墙抗震性能的影响。试验结果表明:该装配式组合剪力墙抗震性能良好;相比于边缘构件和墙体焊接的组合剪力墙,设置竖向通缝的组合剪力墙承载力降低约25%,但延性提高;采用合理的水平缝螺栓连接构造,可保证连接处应力的有效传递。与一字形和锯齿形缝组合剪力墙相比,企口形缝组合剪力墙的承载力较低。In order to improve the construction efficiency of the steel-concrete-steel composite shear walls, a novel type of prefabricated steel-concrete-steel composite shear wall with vertical seams and horizontal bolt connections was proposed. Quasi-static tests on six 1/2 scale models were carried out. The failure modes, hysteretic behavior, strain, stiffness degradation, strength degradation and energy dissipation capacity of specimens were analyzed to study the influence of vertical seams and horizontal bolt connections on the seismic behavior of composite shear walls. The experimental results show that this novel type of prefabricated composite shear walls has good seismic performance. Compared with the composite shear walls with edge members and wall welding, the bearing capacity of the novel type composite shear wall decreases by 25%, but the ductility of the new type composite shear wall increases significantly. Horizontal bolted constructions can effectively transfer loads. Compared with the specimens with straight-shape seams and sawtooth-shape seams, specimens with groove-shape seams have smaller bearing capacity.
