摘　　要：为研究不同轴压比对装配式再生混凝土剪力墙滞回性能的影响,本文应用有限元软件对该种剪力墙进行了拟静力仿真模拟实验和系统性的分析。研究结果表明:轴压比越大,剪力墙的水平承载力越大,但是耗能能力和延性有所下降,轴压比每增加0.1,屈服荷载提高13.2%、峰值荷载提高15.3%,延性系数下降10%;剪力墙在破坏阶段前,轴压比越小,剪力墙的初始刚度越小,刚度退化速度也越快;在实际工程中设计装配式再生混凝土剪力墙结构时,轴压比不宜超过0.4,尽量选用轻型楼盖以降低组合剪力墙的轴压比,可将该结构应用于小高层建筑中。In order to study the influence of different coaxial pressure ratio on the hysteresis performance of the assembled regenerated concrete shear wall,the quasi-static simulation experiment and systematic analysis of the shear wall are carried out by using the finite element software in this paper.The results show that the bearing capacity of the shear walls increases and the ductility decreases with the increase of the axial compression ratio.The axial compression ratio increases by 0.1,the yield load increases by 13.2%,the peak load increases by 15.3%,and the ductility coefficient decreases by 10%.With the decrease of axial compression ratio,the initial stiffness of shear walls decreases and the speed of stiffness degradation is faster before the failure stage.When designed the assembled recycled concrete shear wall structure in practical engineering,the axial compression ratio should be strictly controlled,and the light floor should be chosen as far as possible to reduce the axial compression ratio of the composite shear wall.The axial compression ratio should not exceed 0.4.The structure can be applied to small high-rise buildings through reasonable design.
