摘　　要：提出了新型构造的半装配式、全装配式单排配筋再生混凝土剪力墙,为研究其中高剪力墙的抗震性能,进行了2个半装配式、1个全装配式和1个全现浇单排配筋再生混凝土中高剪力墙试件的低周反复荷载试验,对比分析了各试件的破坏形态、滞回特性、承载力、延性、刚度退化、耗能能力及钢筋应变。结果表明:半装配式单排配筋中高剪力墙与全现浇剪力墙相比,承载力接近,滞回曲线均较饱满,耗能能力相差不大;全装配式试件与半装配式试件相比,承载力低,延性和抗震耗能能力差;随着轴压比的增大,半装配式剪力墙的承载力、耗能能力明显提高。A new type of semi-assembled,fully-assembled single-row RAC shear wall is proposed. In order to study the seismic behavior of this mid-rise shear walls,low cyclic loading test of four specimens has been carried out:two semi-assembled single-row RAC shear wall,one single-row RAC shear wall cast in place and one full-assembled single-row RAC shear wall. The failure characteristic,hysteretic property,load bearing capacity,ductility,stiffness degradation,energy dissipation and reinforcement strain are compared and analyzed. The results show that the load bearing capacity and the energy dissipation capacity of the mid-rise semi-assembled single-row RAC shear wall is close to that of the shear wall cast in place,and the hysteresis curves are full. Compared with the semi-assembled specimen,the fully-assembled specimen has lower load bearing capacity,worse ductility and lower energy dissipation capacity. With the increase of axial compression ratio,the bearing capacity and energy dissipation capacity of semi-assembled shear wall are obviously improved.
