［摘要］通过算例分析比较，对高层框架结构在不同高度设置梁式转换层时的受力及位移特点进行研究。结果表明，带转换层结构与无转换结构相比，转换层以下各层的内力成倍增加，转换层以上各层内力增加较小。转换层不同高度的结构相比，低位转换结构的转换层以下的内力几乎不变，高位转换结构的转换层以上的内力将减小，两转换层之间结构的内力将成倍增加。

Abstract:Three 15-floor tall frame buildings are used to study the bearing capacity and displacement characteristics of high rise structures with the transferring beams at different heights.The calculation results show that,compared with the no transfer story structure,the internal force below the transfer floor increases doubly,and that above the transfer floor increase little.Compared with no transfer story structure,the internal force below the transfer story of structure with low level transfer beams changes little,while that above the transfer story of structure with high level transfer beams diminishes.The internal forces between the two transfer beams increase doubly.

Keywords:tall building;  transfer beam; displacement; analysis
