[摘要]高层剪力墙结构的顶点平动和扭转分别关联着楼层的层间平动位移和层间扭转位移,据此提出了楼层层间位移角的控制策略。研究结果表明:约束高层建筑的结构顶点水平位移来控制楼层最大层间位移角的策略是广泛适用的;依据结构水平变形的形态选择对应的结构布置调整方案,可以高效控制楼层层间位移角的平动分量;限制各楼层的位移比,发挥结构实际侧移刚度,可控制楼层层间位移角的扭转分量。

Abstract:The lateral drift and torsional drift between storys of a high\|rise shear wall building are related to the translational story drift and torsional story drift. A strategy to controlling the story drift ratio was proposed. It points out that the method of controlling the maximum story drift ratio via restraining the translational vertex displacement is feasible. According to the pattern of structural distortion, an appropriate array of structure was selected, which is able to efficiently control the translation component of the story drift ratio; By limiting the torsional drift ration and exerting the potential of the structure′s lateral stiffness can control the torsional component of the story drift ratio.

Keywords:high-rise shear wall structure; storey drift ratio; translational storey drift; torsional storey drift
