摘要
宁夏吴忠黄河文化体育会展中心建筑功能含三大部分:体育场、体育馆和会展中心,总建筑面积约11万m^2。其中体育场钢结构挑篷为一直径234m的圆形,采用悬挑式钢桁架结构体系,最大悬挑跨度31m;体育馆与会展中心共同组成体育会展馆,其屋面钢结构罩棚按建筑功能分为五大部分,分别采用双向或单向钢桁架结构体系,其中体育馆最大跨度达92m。本文分体育场和体育会展馆两大部分,分别介绍了其屋盖钢结构体系及其受力特点,结构计算分析结果及基础设计情况。本项目屋盖结构受力合理明确,结构性能及各项指标满足要求,结构达到了安全、经济的目标。项目已于2018年投入使用。
There are three building functions of Yellow River Culture and Sports Exhibition Center in Ningxia Wuzhong,which are the stadium,the gymnasium and the exhibition center. The total building area is about 110 thousand square meters. The steel canopy of the stadium is a circle whose diameter is 234 m. The cantilever steel truss system is adopted,and the largest cantilever is 31 m. The Sports Exhibition Center is combined by the gymnasium and the exhibition center. Based on the building functions,the Sports Exhibition Center is divided into five parts in which the two directions truss and single direction truss are used respectively. The largest span of the gymnasium is 92 m. The structure system and the characteristics,the analysis result and the foundation design of the steel canopies of the stadium and the Sports Exhibition Center are introduced separately. As a result,the mechanical performance of the roof structure is reliable,and the indexes satisfy the requirement. The roof steel structure is safe and ecnomical. The project has been come into service since 2018.
