摘    要:薄板墙的滞回曲线在零位移附近有零刚度现象,存在明显的捏缩效应,常规方法是直接采用中厚板或通过强大的加劲体系将薄板转化成中厚板,但这将降低薄板墙的经济性。通过两片开洞薄钢板墙低周反复荷载试验,系统地研究了开洞钢板墙的破坏过程和破坏机理,得到了承载力,侧移刚度,延性和耗能能力等指标。试验结果表明,开洞钢板墙有较高的承载力和侧移刚度,延性和耗能能力很好。开洞不仅可以满足门窗洞口等建筑需求,而且可以减小内填板宽度,调节内填板与框架的刚度比,避免薄板墙的捏缩效应,使构件有更高的安全储备,开洞钢板墙是一种理想的水平抗侧力构件。

关 键 词:钢板剪力墙  循环荷载  延性  开洞  捏缩效应

Abstract:The cyclic behavior of the thin steel plate shear wall was generally characterized by hysteretic loops that were pinched at the point of zero displacement.In general,to avoid the pinch phenomena,more thick panels or heavy stiffeners were needed,but they will increase the cost of steel plate and shear walls.A new type of earthquake-resisting element,consisting of a thin steel plate shear wall with opening,was studied.Test results were presented for 2 one-story single bay specimens of roughly one-third of ful...
Keywords:steel plate shear wall  opening  pinch  cyclic loading  ductility
