［摘要］對(duì)懸掛式轉(zhuǎn)換混凝土框架結(jié)構(gòu)進(jìn)行靜力計(jì)算，研究轉(zhuǎn)換體各受力階段的受力特點(diǎn)；以控制轉(zhuǎn)換體變形為目標(biāo)狀態(tài)，建立鋼索張力、轉(zhuǎn)換體撓度的計(jì)算公式。研究結(jié)果表明，懸掛式轉(zhuǎn)換混凝土框架結(jié)構(gòu)無需轉(zhuǎn)換層，轉(zhuǎn)換體內(nèi)的框架梁、柱均為正常截面高度，其樓層側(cè)向剛度變化較為均勻、無大的突變，有利于結(jié)構(gòu)抗震，可用于20～30m跨度的框架結(jié)構(gòu)轉(zhuǎn)換。

Abstract:The static calculation of the suspension transfer concrete frame structure was conducted to study the stress characteristics of the transfer body at each mechanical stage. In order to control the deformation of the transfer body as a target state, a calculation formula for steel cable tension and deflection of the transfer body was established. The results show that the suspension transfer frame structure does not need a transfer layer, and the frame beams and columns in the transfer body are  normal section height, and the lateral stiffness of the floor is uniform without big abrupt change, which is beneficial to structural seismic ability and can be used for 20～30m span frame structure transfer.

Keywords:suspension transfer frame structure; transfer body; redistribution of internal forces; envelope design; iteration calculation; initial tension state; target status
