摘　　要：采用ANSYS有限元程序对两边连接钢板剪力墙与钢板组合剪力墙进行数值模拟分析.研究了不同高厚比下两边连接钢板剪力墙与钢板组合剪力墙抗剪静力性能的区别,分析了两种剪力墙的受力机理和破坏模式.结果表明:高厚比λ是影响两边连接钢板剪力墙抗剪静力性能的主要因素;高厚比较大的剪力墙所需要的能够完全限制钢板出平面方向位移的混凝土板厚度较小;预制混凝土板的存在改变了剪力墙钢板的受力模式,对薄钢板剪力墙尤为明显,钢板由拉力带承担水平荷载改变为截面受剪承担水平荷载.In this paper the numerical simulation on steel plate shear wall（SPSW） and steel-concrete composite shear wall（SCSW） with two-side connection was carried out by the finite element software ANSYS.Performances of the two shear walls were investigated.Different mechanical behaviors between SPSW and SCSW with two-side connection were discussed in details.It is found that the depth-thickness ratio λ is a key parameter that influences the shear resistance behavior of SPSW with two-side connection.The concrete plate which completely restricts the out-of-plate displacement may be thin if the depth-thickness ratio of a wall is large enough.Due to the concrete plate supporting,stress distributions in the SCSW are changed obviously：the horizontal load transferring manners are changed from tension strip to cross-sectional shear in the steel plates.
