Analysis of Steel Roof and Canopy in Guangxi Culture and Art Center

广西文化艺术中心是南宁市标志性项目,由大剧院、音乐厅、多功能厅组成。建筑外形为表现广西喀斯特地貌的山体造型和漂浮于山腰的云带,山体造型由平行的平面拱桁架构成,云状雨篷由平行的平面桁架组成。雨篷桁架与3个大厅的拱结构连为一体,与混凝土结构设抗震缝脱开。钢屋盖与雨篷形态复杂、受力独特,对相关设计内容作了详细介绍,论证了结构的安全性。

Guangxi Culture and Art Centre is the landmark project of Nanning City.It consists of grand theater,concert hall and multifunction hall.The architectural shape expresses mountains of typical karst landform in Guangxi and the cloud belt at the middle of mountains.The shape of‘mountains＇ is structurally formed with parallel arch trusses,and the shape of‘cloud belt＇is formed with parallel plane trusses.The trusses in cloud shape are connected with the arches of each individual building,which are separated from concrete structure with seismic joint above platform.The external steel structure system is rather complicated,with unique stress state.This paper provides detailed introduction on the structural design and proves the safety of the structure.
