摘　　要：通过对高位拱式转换层结构分别采用振型分解反应谱法和时程分析法进行计算,研究了这种新型转换层结构的地震反应。结果表明,结构的自振周期随转换层位置的上移,变化较小。转换层位置的改变,并没有引起结构振型曲线显著变化。转换层上、下部结构楼层剪力随着转换层位置的上移,变化规律基本一致。转换层上部结构的层间位移角变化规律基本一致,层间位移角并没有随转换层位置的提高而发生突变。转换层下部楼层的层间位移角随着转换层位置的提高而增大。The seismic response of high arch-transfer story transfer story has been studied,by using mode-superposition response spectrum method and time history analysis method.The results show that the natural period of the structure has little change with the shift of the transfer story＇s location.The structural vibration curve hasn＇t changed significantly with variation of the transfer story＇s location.The shear of the upper and lower floor of the transfer story＇ variation is the same with the shift of the transfer story＇s location.Besides,with the shift of the location of the transfer story,the angle of story drift of the top floor of transfer floor＇s varition is the same and undistributed.And the angle of story drift of the bottom floor of transfer floor may be increased when transfer floor located at a higher level.
