肇庆新区体育中心工程由专业足球场、体育馆(包括主馆、训练馆及其连接部位城市客厅)组成。各单体主体采用钢筋混凝土框架结构;专业足球场屋盖为悬挑钢箱梁结构;体育馆主馆和训练馆屋盖为双连体弦支穹顶结构。主要介绍肇庆新区体育中心结构体系的确定、大跨度钢屋盖体系设计、结构抗震设计、基础设计以及混凝土耐久性设计。采取设计、材料及施工等层面的有效措施,解决各单体结构超长、温度应力及混凝土收缩应力较大的问题。下部混凝土结构和屋盖钢结构计算结果均能满足规范要求。
Zhaoqing New District Sports Center project by the professional football stadium, gymnasium (including the main hall, training hall and the connection part of the city living room). The main body of each monomer reinforced concrete frame structure; professional football stadium roof cantilevered steel box girder structure; gymnasium main gymnasium and training gymnasium roof for the double-string structure. Mainly introduces the structural system of Zhaoqing New District Sports Center, the design of long-span steel roof system, the design of seismic structure, the basic design and the durability design of concrete. To take the design, materials and construction and other aspects of effective measures to solve the long structure of the monomer, temperature stress and concrete shrinkage stress larger problem. The calculation results of the lower concrete structure and roof steel structure can meet the requirements of the specification.
