考虑几何非线性和面外初始缺陷,通过变化内嵌钢板的高厚比λ,考察了钢板墙与防屈曲组合钢板墙在水平荷载作用下的承载力、抗侧刚度和滞回性能的差异,并对比分析了两种墙体的内嵌钢板与边缘框架柱的相互作用。结果表明,随λ由大到小变化,钢板墙可分为薄钢板墙、中厚钢板墙和厚钢板墙三类;由于受到面外约束的作用,与钢板墙相比,防屈曲组合钢板墙具有更好的抗剪承载力和耗能能力,利用防屈曲组合钢板墙替代中厚钢板墙和薄钢板墙是经济可行的,且不存在因屈曲后拉力场效用对边柱产生的附加弯矩作用,更有利于实现“强框架弱墙体”的延性设计。
Considering the geometric nonlinearity and the initial out-of-plane flaw, the difference of bearing capacity, lateral stiffness and hysteretic behavior of the combined steel plate wall and the anti-buckling composite steel plate under horizontal load was investigated by changing the ratio of height to thickness of embedded steel plate. And the interaction between the two kinds of wall embedded steel plate and the edge frame column is analyzed. The results show that with the change of λ from small to small, the steel wall can be divided into three categories: thin steel wall, medium steel wall and thick steel wall. Compared with the steel wall, Has better shear capacity and energy dissipation capacity. It is economically feasible to replace the medium-thickness steel plate wall and the thin steel plate wall with anti-buckling composite steel wall, and there is no additional bending moment due to the pulling field effect after buckling Role, but also more conducive to achieve “strong frame weak wall ” ductility design.
