[提要]  通过风洞模拟的方法研究了芜湖体育场东（副）、西（主）看台不对称索膜结构挑篷的风荷载特性。试验结果表明：当主看台挑篷处于斜下风向位置时的风荷载要比类似的对称挑篷大许多。局部负压峰值通常出现在伞状膜单元尖顶附近和主看台的檐口部分。

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
