Experimental Studies on Seismic Behavior of Double-Skin-Composite Shear Walls

  • 摘要: 双钢板-混凝土剪力墙在工程中被广泛应用,但国内对超高层建筑双钢板-混凝土剪力墙面内抗剪性能的研究相对较少。本文根据实际工程制作了6组1:3缩尺比例的中低剪跨比双钢板-混凝土剪力墙试件,开展了面内低周水平往复加载拟静力试验,得到了试件的滞回曲线等主要特性曲线,并分析了轴压比、钢板与混凝土墙间的连接形式等因素对双钢板-混凝土剪力墙抗剪性能的影响。试验结果表明:6组试件都呈现出剪切破坏特征;钢板与混凝土之间剪力连接件中对拉钢筋所占比例对试件的面内抗剪性能影响较小;试件的变形能力和延性随轴压比的增大而减小,在试件加载后期,轴压比越大的试件等效黏滞阻尼系数越大;混凝土强度对试件加载初期的变形能力影响较大,但对极限状态下的变形能力影响较小;剪跨比对墙体变形能力、承载力和刚度影响明显;试件的耗能曲线均呈指数型增长,表明双钢板-混凝土剪力墙抗震性能更优越。
