Research on the effect of vertical position of stagger transfer stories on the dynamic characteristic and seismic behaviour of structures

摘要

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 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 effect 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 change will appear in the internal force of the vertical components near the two stagger transfer stories, it should be considered during designing.
