广西体育中心主体育场结构设计

Structural design on the main stadium of Guangxi Sports Center

介绍了广西体育中心主体育场的结构体系及钢结构罩篷的结构设计。钢结构罩篷采用平面桁架+环向支撑组成的空间钢管桁架结构,简化了杆件布置和节点设计。经过对结构进行静力分析、风荷载及地震作用分析、温度作用分析、屈曲稳定分析、关键节点计算分析和试验,验证了结构设计的可靠性。

The structure system of the main stadium of Guangxi Sports Center and the steel structural design of the canopy were introduced. The structure arrangement and joint design were simplified with the use of the spatial steel tube truss which is composed of the planar truss and the lunar supporting. In order to verify the reliability of structural design, the static elastic analysis, wind and seismic action analysis, temperature action analysis, buckling stability analysis, analysis and experiment of the key joints were carried ont.
