摘　　要：本文采用有限元程序对设有错位转换的高层结构进行了空间时程地震反应分析,论述了错位转换层整体位置、错位转换层相对位置对结构动力特性、动力反应及竖向构件内力的影响。分析结果表明,错位转换层整体位置的变动及相对变动对结构周期、主要振型和相对位移影响不大;随着错位转换层整体向上移动,在转换层处的层间位移角的突变会加剧;当两错位转换层相距3层左右时,高层结构地震反应最不利;错位转换层的存在会使两错位转换层附近的竖向构件内力发生突变,设计中应予以加强。For a high-rise building with stagger transfer stories, the effect of the position and relative position of stagger transfer stories on dynamic properties, seismic response and internal force of vertical component is discussed. The various levels of the whole stagger transfer stories have little effect on the periods, main modes and relative displacement of the high-rise building. When they are on the higher story, the sudden change of drift-angle near the transfer story will be increased. When the distance between the two stagger transfer stories is about 3 stories, the interaction of them will be the greatest. When there is stagger transfer story in the high-rise building, the sudden change will appear in the internal force of the vertical components near the two stagger transfer stories. It should be considered during designing.
