组合剪力墙的滞回性能研究

组合型钢剪力墙刚度大、延性好,在土木工程中应用广泛。组合型钢剪力墙一般通过铺设与钢板连接的混凝土层或纤维增强复合板形成。本试验和数值研究主要分析剪力钉间距、中间梁刚度、梁柱连接方法对组合型钢剪力墙性能的影响。结果表明:增大剪力钉间距可减小荷载-位移曲线的斜率,并提高结构韧性。中间梁刚度和梁柱连接对组合型钢剪力墙性能的影响是非常微小的,可以忽略。

Evaluation of Composite Shear Wall Behavior Under Cyclic Loadings

Composite steel shear walls (CSSW) are widely used in civil projects due to its high stiffness and deformability. It can be utilized by either laying a concrete layer connected to the steel plate by shear studs or bonding a Fiber Reinforced Polymer sheet. The present experimental and numerical investigations were focused on the effects of shear studs spacing variation, middle beam rigidity and the method of beam to column connection on the CSSW behavior. Results indicate that increasing the shear studs spac...
