Abstract：There are little literatures about vertical dynamic characteristic and seismic performance on high-rise building with stagger transfer stories, in this paper, one coming from practical project will be studied with SAP2000V9 program. The effect of number of vertical modes on the internal force of the upper, lower transfer beam and the axis-force of main vertical components are studied. Vertical acceleration, vertical drift and vertical dynamic strain are computed, the dynamic response at the end point, column point on the upper, lower transfer beams with different stories are researched and compared when earthquake waves and spectrum are input. The axis-force of the columns on the upper, lower transfer beams, supporting shear wall, shear wall supported by frames, columns supporting shear walls are calculated when earthquake waves and spectrum are input, and compared to the value under the representative gravity load. The result shows the basic vertical modal plays a very important role in effect on the internal force of transfer beams and the axis-force of main vertical components, the modals above the 5th modal have little effect on them; the displacement and acceleration at the column point on the transfer beam are greater than those at the end points of the upper, lower beams; the vertical strain of the vertical component at the end point of the upper, lower transfer beams have sudden change at the stories which are just above the two transfer stories respectively, simultaneously the vertical strain of the vertical components at the stories between two stagger transfer structures increase partially; the higher the location of the vertcial component is, the greater the versus between the internal force of it under the spectrum load and that under the representative gravity load; under the vertical earthquake, the axis force of supporting shear wall at the top story and that of shear wall supported by frames at the three bottom stories will occurs sharply change.
