摘要
过去的几十年中,在世界范围内钢板剪力墙已经作为一种新型的抗侧力体系在高层建筑中得到了应用,已有大量试验针对在水平荷载作用下无加劲肋平面薄钢板剪力墙进行研究。对高厚比约为400,比例为1∶3的两个单层单跨十字加劲肋钢板剪力墙在低周反复荷载作用下的抗震性能进行研究,重点研究了钢板墙抗剪承载力、变形能力、破坏特征、构件延性和耗能能力等受力特性。试验结果表明:试件具有较大的初始刚度,并且具有很好的延性以及耗能性能。可为钢板墙结构利用屈曲后强度及抗震设计提供依据。
In the past several decades, steel plate shear walls have been introduced as primary lateral load resisting elements in several buildings around the world. Lots of tests have been done to investigate unstiffened thin steel-plate shear waIIs（SPSW） under lateral loads. Low cyclic loading experiment of two 1：3 scale specimens of one-bay single story shear wall models with panel slenderness ratio of 400 is also studied. It was inquired into the capacity of shear force and distortion,the damage state, the ductility features and the energy-dissipating capacity etc.Test results indicated that the test specimen proved to be initially very stiff , showed excellent ductility and energy dissipation characteristics, which provided a base for utilizing post-buckling strength and seismic design of SPSW.
