平面L形高层建筑的扭转效应分析及对策

Torsional Analysis and Countermeasures for High-Rise Buildings with L Shape Plan

平面L形高层建筑结构的刚度中心与质量中心偏离较大,在水平地震作用下平移振动与扭转振动扭耦合。分析由于耦合导致扭转效应动力增大的主要因素。

Torsional and lateral vibration of a high-rise building with L shape plan under earthquake will couple because of large distance between center of stiffness and center of mass. Main factors to enlarge the torsional response induced by coupling action are analysed. The countermeasures to reduce the torsional effect are provided through the examples.
