摘　　要：采用ANSYS软件分析了预制混凝土板厚度和混凝土强度对钢板混凝土组合剪力墙承载力及初始剪切刚度的影响,通过与钢板剪力墙对比,探讨了钢板混凝土组合剪力墙的受力机理和破坏模式。研究结果表明:与钢板剪力墙相比,预制混凝土板能够有效地抑制钢板屈曲,明显地提高钢板混凝土组合剪力墙抗剪承载力及初始剪切刚度,钢板的受力形式也发生了明显的变化。The commercial software ANSYS was employed to investigate the mechanical behavior of steel-concrete composite shear wall （SCSW） under mono-static load. The influences of concrete-plate thickness and concrete strength on SCSW ultimate bearing capacity and SCSW initial shear stiffness were discussed in detail after comparison of the mechanical behavior of the two types of shear walls. The research results show that concrete-plate thickness is a key parameter to predict the behavior of SCSW, and variation of concrete grade has little effect on static behavior of SCSW.
