赤峰体育中心体育场下部采用钢筋混凝土框架结构,挑篷采用平面管桁架结构。对屋盖大悬挑平面管桁架进行了风洞试验以确定风载计算参数。本文主要介绍了主体混凝土结构设计、屋面挑篷的结构选型和分析设计,阐述了复杂结构建模分析设计、风洞试验、超长结构设计等关键问题。
The lower part of Chifeng Sports Center Stadium adopts reinforced concrete frame structure, and the canopy adopts a flat tube truss structure. Wind tunnel tests were carried out on the large cantilevered plane roof truss to determine the wind load calculation parameters. This paper mainly introduces the design of the main concrete structure, the structure selection and analysis of the roof canopy, and expounds the key issues of the complex structure modeling and analysis, wind tunnel test, long structural design.
