摘　　要：通过算例分析比较 ,对高位转换层结构的抗震性能和受力特点等进行了研究。结果表明 ,当转换层位置逐渐上移时 ,由于转换层质量较大 ,结构的振型地震作用在转换层处有明显增大 ,但结构周期及振型仅有一些量的变化 ,楼层的地震剪力和弯矩在转换层以下楼层也有所增大 ,结构抗震计算时 。This paper discusses the structural and seismic behavior of transfer floor located at a higher level in the tall buildings.It shows with the height of transfer floor increasing,the mode seismic action at transfer floor is increased evidently because of the greater mass of the transfer floor,but the natural period and vibration mode of the whole structure is changed a little,and the seismic shear and moment of stories below transfer floor are increased.It is pointed out that the mode number needs to be added in analyzing seismic action as well as internal forces of the structural components.
