摘要
以株洲体育中心大跨屋盖结构为背景,采用CFD数值模拟方法,模拟了大跨屋盖表面风荷载,并与大跨屋盖结构风振时程响应进行了分析比较.结果表明:采用CFD方法模拟的大跨屋盖结构表面平均风荷载与风洞试验结果比较接近,说明该法是比较精确的,所提供的体育馆及游泳馆屋面的体形系数可以提供为结构设计参考.
With CFD numerical method, based on the result of wind pressure measurements test of long-span roof of Zhuzhou Sports Center, the mean wind load of the long-span roof structure is simulated. The simulated results are analyzed and compared with the wind tunnel results. The results indicate that CFD numerical results are approaches to experiment results. The conclusions are helpful for designers.
