循环荷载下组合剪力墙的性能评估

组合钢板剪力墙(CSSW)由于其具有极高的刚度及可变性,在土木工程领域内应用广泛。它可以用于混凝土覆层,与钢板采用剪切螺钉连接,或者与FRP板黏结。现有的试验和数值研究集中在剪切螺钉间距变化时,梁跨中刚度和梁柱连接方法对组合钢板剪力墙的影响上。结果显示:剪切螺钉间距的增加使荷载-位移曲线斜率减小,改善了由特定螺钉间距影响的延性。此外,梁跨中刚度和梁柱节点对组合钢板剪力墙也有很显著的影响。

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...
