摘要
李渡新区体育中心体育场钢结构罩棚由两片月牙造型的空间结构组成,采用骨架和张拉相结合的膜结构,主受力结构由带大型拉压杆的立体桁架和跨度245.6 m的拱桁架组成。工程设计难点为场地限制造成的拱结构平面外弯折,结合具体的结构设计,详细介绍罩棚结构的静力、动力性能和拱结构方案的选择,分析温度荷载和风荷载对大跨度结构的影响。
The combination of skeleton structure and tension membrane structure is adopted in the roof of Lidu New District Sport Center Stadium which comprises two crescent-type spatial structures. The main structure is composed of spatial truss, which consists of large tension bars and compression bars, and arch truss with 245.6 m span. The difficulty in this project is the outerplanar bending of the arch truss due to the limitation of the site. Combining the specific structure design,the static and dynamic performance and optimizations of structural design were introduced in detail. The effects of temperature and wind load on large-span structure was also analyzed.
