［摘要］通過算例分析比較，對高層框架結(jié)構(gòu)在不同高度設(shè)置梁式轉(zhuǎn)換層時的受力及位移特點進行研究。結(jié)果表明，帶轉(zhuǎn)換層結(jié)構(gòu)與無轉(zhuǎn)換結(jié)構(gòu)相比，轉(zhuǎn)換層以下各層的內(nèi)力成倍增加，轉(zhuǎn)換層以上各層內(nèi)力增加較小。轉(zhuǎn)換層不同高度的結(jié)構(gòu)相比，低位轉(zhuǎn)換結(jié)構(gòu)的轉(zhuǎn)換層以下的內(nèi)力幾乎不變，高位轉(zhuǎn)換結(jié)構(gòu)的轉(zhuǎn)換層以上的內(nèi)力將減小，兩轉(zhuǎn)換層之間結(jié)構(gòu)的內(nèi)力將成倍增加。

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
