摘要
大量震害表明,结构在地震发生时存在着扭转振动,且结构的平扭耦合效应不可忽视,在某些情况下甚至是结构破坏的主因。本文对某平面不规则高层建筑结构的1/30模型模拟振动台试验数据和理论计算进行了对比分析。
Lots of earthquake disaster phenomena show that structures with torsion modes of vibration have obvious torsions under seismic action, which are occurred together with translational vibration of structures. In certain cases, torsion can be the main action of the structural damage. The contrast between theoretical calculation and experiment of seismic performance analysis of horizontal irregular high structure by the 1/30 model on a shaking table are given.
