摘　　要：平面不规则的高层建筑结构在地震作用下会发生扭转振动效应。通过合理布置结构平面,减小结构的质心与刚心的距离,合理控制一阶扭振周期与一阶侧振周期的比值,可以有效地减小结构的扭振效应。结合上海金轩大邸7号楼结构设计,介绍了合理有效地减小平面不规则高层剪力墙结构的扭转效应的方法。Earthquake can cause torsional vibration to high-rise structures with irregular plane.This response of torsional vibration can be decreased by properly arranging the structural plane,reducing the distance of mass and stiffness centre of the structure,properly controlling the ratio of the first-order torsional vibration period to the first-order lateral vibration period.The paper introduces the way to reduce the response of irregular high-rise shear wall structure torsional vibration with the example of structural design of N0.7 Jinxuan Building in Shanghai for reference of structure designers.

关 键 词：剪力墙结构 平面不规则 抗扭刚度 扭转振动效应
