［摘要］对悬挂式转换混凝土框架结构进行静力计算，研究转换体各受力阶段的受力特点；以控制转换体变形为目标状态，建立钢索张力、转换体挠度的计算公式。研究结果表明，悬挂式转换混凝土框架结构无需转换层，转换体内的框架梁、柱均为正常截面高度，其楼层侧向刚度变化较为均匀、无大的突变，有利于结构抗震，可用于20～30m跨度的框架结构转换。

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
