【摘要】 作为一种新型转换层结构——错位转换层结构,其竖向位置的变化对高层结构在水平地震作用下的动力特性和抗震性能影响的研究尚鲜有文献报道.文章采用有限元(FEM)程序对高层错位转换结构进行了水平地震作用下抗震性能分析.分析研究发现,错位转换层整体位置的竖向变化对结构周期、主要振型和相对位移影响小.当错位转换层位于较高楼层位置时,转换层附近的层间位移角的突变程度会加大.对错位转换高层结构,水平地震作用下两错位转换层附近楼层竖向构件内力会呈现突变,因此,设计具体结构时应引起注意.更多还原

【Abstract】 As a special new type of transfer structure-stagger transfer structure,the literature on the vertical position’s effect on the mechanic behavior of vertical component can’t be found.A FEM(finite element method) program is used to analyze the horizontal seismic response of high-rise building with stagger transfer structure.The various levels of the whole stagger transfer stories have little effects on the periods,main modes and relative displacement of the high-rise building.When they lie at the higher story,the sudden change of drift-angle near the transfer story will be hardened.When there are stagger transfer stories in the high-rise building,sudden changes will appear in the internal forces of the vertical components near the two stagger transfer stories,and it should be considered during designing.更多还原
