［摘要］为探讨超高层钢筋混凝土转换结构计算层高选取的合理性，以重庆江北嘴金融城4号项目转换结构为例，选取4种层高划分模型与实体单元模型进行对比分析。分析结果表明，在进行此类结构抗侧刚度计算时，转换层层高取“转换梁T形截面形心线以下高度+转换层净高”，转换层上一层层高取上部楼层实际层高，更为接近结构实际性能。

Abstract:For researching the rationality of selection of calculation story height of transfer structure in super high-rise reinforced concrete building, the transfer structure in the No.4 project in Financial City of Jiangbeizui region in Chongqing was taken as example, and four calculation models of different calculation story heights and a model of solid elements were analyzed and compared. Analysis results show that when calculating lateral stiffness of this kind of structure, transfer story height adopts the value of height below the centroid line of transfer beam′s T-typed cross-section plus clear height of story, and the upper story height adopts the value of actual height, to get more real performance of the structure.

Keywords:transfer structure; super high-rise; lateral stiffness; stiffness ratio
