[提要]  通過風(fēng)洞模擬的方法研究了蕪湖體育場(chǎng)東（副）、西（主）看臺(tái)不對(duì)稱索膜結(jié)構(gòu)挑篷的風(fēng)荷載特性。試驗(yàn)結(jié)果表明：當(dāng)主看臺(tái)挑篷處于斜下風(fēng)向位置時(shí)的風(fēng)荷載要比類似的對(duì)稱挑篷大許多。局部負(fù)壓峰值通常出現(xiàn)在傘狀膜單元尖頂附近和主看臺(tái)的檐口部分。

By means of wind tunnel simulation, wind loading characteristics on asymmetric membrane cantilever structure roof of Wuhu stadium are given. Experimental results show that when the main-bleachers membrane cantilever structure roof locates downstream in oblique wind direction, the load is much larger than that of symmetric one. The local negative peak pressure usually locates at vicinity of the sharp top of the membrane cell and leading eaves of the main bleachers.
Keywords:  wind tunnel simulation; membrane structure; cantilever structure roof
