［摘要］北京嘉铭中心基础设计采用变刚度调平设计方法，减小了基础的差异沉降；上部结构设计时，通过增强结构的抗扭刚度解决了核心筒偏置造成的扭转问题；两座塔楼之间的83m高中庭采用索网幕墙，与主楼滑动或铰接连接。两座塔楼之间的连桥采用轻型张弦梁结构体系。［关键词］北京嘉铭中心; 变刚度调平; 核心筒偏置; 多塔; 连体结构; 弱连接中图分类号：TU318 文献标识码：A 文章编号：1002-848X(2016)07-0014-05
Structure design of Beijing Jiaming CenterHan Ping, Pan Ning, Zhu Huosheng, Sun Jianchao, Wang Liqiang(China Academy of Building Research, Beijing 100013, China)Abstract: The variable rigidity design method was used in the foundation design of Beijing Jiaming Center to reduce the differential settlement of the foundation.During the upper structure design process, structural torsion stiffness was enhanced to solve the problem of torsion due to corewall bias. High atrium with height of 83m between two towers adopts cable-net curtain wall which is connected with the main building in form of sliding or hinged connection. The bridge between the two towers adopts the structural system of light beam-string structure.Keywords: Beijing Jianming Center; variable rigidity; corewall bias; multitower; connected structure; weak connection
