摘　　要：为研究不同配筋形式和不同轴压比下全轻混凝土剪力墙的动力特性,对4片全轻混凝土剪力墙试件在拟静力试验下采用锤击方法激振加速度信号,通过对比获得的振型、频率及阻尼比等参数,分析全轻混凝土剪力墙结构在不同损伤程度下的抗震动力特性,为实际工程运用提供理论基础。研究结果表明:随着轴压比增大,结构频率增大,阻尼比减小;斜向支撑钢筋对全轻混凝土剪力墙的阻尼比及频率无明显影响。For the research on the dynamic characteristics of different reinforcement forms and different axial com- pression ratio under lightweight concrete shear wall, 4 pieces of whole lightweight concrete shear wall specimens with hammering method of vibration acceleration signal parameters are tested. The frequency and damping ratio of these wall specimens are obtained by comparing the analysis. In the structure under different damage degrees, the anti-earthquake dynamic characteristics of lightweight concrete shear wall are obtained. A theoretical basis for the practical engineering application is provided. The results show that with the increase of the axial compression ratio, the structure frequency increases and the damping ratio decreases. The damping ratio and full light frequency of the diagonal bracing of reinforced concrete shear wall are not affected obviously.
