备注

为研究密肋网格约束型钢板剪力墙结构的抗震性能,通过对一榀密肋网格约束型钢板剪力墙结构的拟静力试验研究,获取了结构的滞回曲线、骨架曲线及各阶段荷载和位移值.试验分析了结构的破坏模式,滞回性能、延性、承载能力及耗能等抗震性能指标.试验结果表明:密肋格板将钢板分成小区格板件,减小了墙板的高厚比,有效规避了薄板墙的声响和震颤现象,避免了滞回环体的捏缩现象,降低了边框柱的破坏程度.墙板变形以小区格板件的局部屈曲为主.

In order to study the seismic behavior of ribbed grid restrained steel plate shear wall structure, a one-bay experimental specimen of steel plate shear wall structure with ribbed grid restrained was tested under the quasi-static loading,the hysteretic curves, skeleton curves and load and displacement values of each stage were obtained. Seismic properties, such as the failure mode, hysteretic behavior, ductility, bearing capacity and energy dissipation capacity were evaluated in the experiment. The results show that the steel plate was divided into several cell plates by the multi-rib stiffeners, reducing height-thickness ratio of the steel plate, lessening the noise and tremor of panels, moreover, avoiding the pinching phenomenon of the hysteretic loops, alleviating the failure of boundary column. The deformation of wall plate is mainly based on local buckling of cell plate parts.
