摘要

摘要: 提出一种适用于钢框架结构体系的新型组合钢板剪力墙形式。对4种宽厚比的纯钢板和1种组合钢板剪力墙单元的静力加载试验的结果表明:宽厚比决定了钢板初始抗侧性能和屈曲模态;小宽厚比钢板对边界约束条件较为敏感;预制墙板对提高剪力墙单元抗剪承载力和提高屈曲荷载有一定帮助,但是对钢板抗侧性能的贡献不大。通过数值模拟增加影响参数,对新型组合钢板剪力墙单元进行了理论分析。最后给出了三边固接一边弹性约束的钢板及组合钢板剪力墙单元的抗剪承载力计算公式,并依据成品预制墙板的规格尺寸给出了组合钢板剪力墙适用的预制墙板最小厚度选择方法。

Abstract: A novel type of steel plate composite shear wall was presented.Four steel plate shear walls specimens and one composite shear wall with various ratio of width-thickness were tested by jack.The failure mode,the shear strength,the lateral stiffness,and the buckling mode were investigated by experiment.The results indicated that ratio of width-thickness of steel plate would determine the shear-carrying capacity and failure mode;and the small ratio of width-thickness of steel plate required adequate anchorage to avoid failure of boundary;although the lateral stiffness of steel plate has little enhancement by the precast concrete plate,the buckling strength and shear strength of steel plate wall were improved by them.Through theoretical analysis,the formula of shear strength of steel plate wall with trilateral constrained and one elastic restraint side,and the one of composite shear wall were proposed based on experiment and numerical simulation.At last,the thicknesses of precast concrete plate applied to steel plate wall with various ratio of width-thickness were presented.
