西安曲江国际会议中心结构设计

Structural design of Xi'an Qujiang International Congress Center

西安曲江国际会议中心结构体型复杂,结构平面及竖向布置均不规则,属特别不规则类型建筑,是集混凝土、钢结构、型钢混凝土、钢管桁架等多种材质及构件为一体的大型综合体建筑。介绍了这一项目的结构特点。设计中采用了40m跨的型钢混凝土桁架作为竖向转换构件,并从计算和构造上予以加强;运用多种不同形式的空间钢管桁架构成高低起伏的波浪形屋面;主桁架的支座采用了部分滑动支座,克服了温度应力的影响。

Xi＇ an Qujiang International Congress Center is a complex irregular structure with irregular arrangements in horizontal plane and vertical plane. Various materials and members were adopted in this project such as concrete, steel, steel-reinforced concrete and steel tube truss. The structure characteristics of this project were introduced. A steel-reinforced concrete truss of 40m span was adopted as vertical transfer member that should be reinforced in design and details. Various forms of spatial steel tube truss were used to form a large-span curved truss roof. The main truss adopts sliding supports in some parts to release thermal stress effects.
