广州新图书馆南北楼连体结构设计关键技术研究

Key technology research on connecting structures of the south-north building of Guangzhou New Library

广州新图书馆为相互倾斜的双塔楼框架连体结构,通过对连接构件在垂直和水平荷载下的变形、内力特性进行深入的分析,提出连接体在罕遇地震下满足弹性状态的性能化设计目标。研究连接体与两端框架的连接方式,保证结构整体安全,分析连体结构之间的变形对幕墙的影响,提出幕墙和光棚适应变形要求的指标。重点介绍该工程连接体部分设计及关键部位的处理方法。

Guangzhou New Library is a frame connecting structure of double-tower inclined each other. By analyzing connective structure＇s distortion and internal force under vertical and horizontal load, seismic performance objectives of connective structures were put forward, which is achieving elastic state under rare earthquake. Connection mode between connective structure and main frame was researched, the safety of the whole structure was assured. The effect of connective structure＇s distortion on curtain wall was analyzed, target data of curtain wall and skylight＇s distortion were put forward. The overall design of connective parts and the special schemes for the key parts were introduced.
