肇庆新区体育中心结构设计

Structural design on Zhaoqing New District Sports Center

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 is composed of a professional football stadium, a gymnasium （including a main gymnasium, a training hall and city living room connecting the main gymnasium and the training hall）. Every individual building adopts the reinforced concrete frame structure. The roof system of the professional football stadium is the cantilever steel box girder structure, and the roof systems of the gymnasium and the training hall adopt the suspendome structures. The determination of the structural system, large-span steel roof system design, the structural seismic design, the foundation design and the concrete durability design were mainly introduced for Zhaoqing New District Sports Center. Effective measures in aspects of the design, material and construction were taken to solve the problems of super-long individual structure, temperature stress and concrete shrinkage stress. The calculation results of the lower concrete structure and the roof steel structure can meet the requirements of the specifications.
