摘　　要：全轻混凝土作为一种轻质高强材料,表观密度小是其最突出特点。为研究全轻混凝土剪力墙在不同配筋形式和不同轴压比下的抗震性能,对4片全轻混凝土剪力墙试件作拟静力试验,分析全轻混凝土剪力墙的破坏机理、延性及滞回性能,为实际工程运用提供理论依据。研究结果表明:随着轴压比增大,结构承载力增大,但延性减小,抗震性能减弱;采用斜向配筋形式全轻混凝土剪力墙的承载力和变形性能高于普通配筋形式全轻混凝土剪力墙。All-lightweight aggregate concrete as a kind of light weight and high strength material, the most outstanding characteristic is its apparent density is small. To research the seismic performance of all-lightweight aggregate concrete shear wall under the different reinforcement forms and axial compression ratios, this paper takes the pseudo-static testing for four pieces of all-lightweight aggregate concrete shear walls to analyse their failure mechanism, hysteretic behaviors and ductility performance, playing a theoretical foundation for the actual engineering application. The research results showed that with the axial compression ratio increases, the structure bearing capacity in- creases, but at the same time, ductility performance decreases, the seismic performance weakened. Using the diagonal reinforcement form of all-lightweight aggregate concrete shear wall bearing capacity and deformation capacity is higher than the ordinary reinforcement form of all-lightweight aggregate concrete shear wall.
