【摘要】 拱式转换层结构是一种新型转换层结构形式,通过算例分析比较,对高位拱式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,结构周期及振型仅有一些量的变化,而没有质的变化;随着转换层位置的提高,转换层本身的层间位移角变化较小,表明其转换层本身的整体性很强,转换层下部楼层的层间位移角增大,因此结构设计时,转换层不宜设置过高。更多还原

【Abstract】 The arch transfer story structure is a new type of transfer story structure.The dynamical characteristics and seismic response behavior of arch transfer story structures with different levels of transfer story on high position have been studied.The results show that with the level of transfer story increasing,the natural period and vibration mode of the structure change a little,and the change of inter-story drift angle of the transfer story is small,and that the transfer story in itself is rigid.And the inter-story drift angles of the storys below transfer story increase when transfer story located at a higher level.Therefore,the level of transfer story should not be too high in structure design.更多还原
