摘　　要：为了研究再生混凝土剪力墙的抗震性能,进行3片取代率为100%的再生混凝土矮剪力墙的低周反复荷载试验研究,在3个试件的高宽比均为1.0,配筋率均相等的情况下,对不同轴压比试件的破坏形态、承载能力、延性、刚度和耗能性能等进行了对比研究。试验研究表明:轴压比是影响再生混凝土剪力墙抗震承载能力的重要因素,随着轴压比增大,剪力墙刚度增大,承载能力增大,但延性和耗能性能降低,抗震性能降低。In order to investigate the seismic performance of recycled aggregate concrete shear wall un- der low-reversed cyclic loading, three specimens of low recycled aggregate concrete shear wall with 100% replacement ratio of coarse aggregate are studied. Under the conditions of a shear-pan ratio of 1. O, the same reinforcement and different axial compression ratio, the failure pattern, load-carrying ability, ductility, stiffness and energy dissipation of the specimens are compared and analyzed. The experimental results shoW that the axial compression ratio of recycled aggregate concrete shear wall is an important factor to the load-carrying ability of the wall. When the axial compression ratio increa- ses, the stiffness and load-carrying capacity Of the wall increase, but the ductility and energy dissipa- tion decrease, and the seismic performance is poorer at the same time.
