| 摘 要： | 以杭州游泳馆膜结构屋顶为例，本文通过风洞模拟实验的方法研究了大坡工膜结构屋面的风荷载特性。研究结果表明，此类结构的风荷载特性具有一定的规律。并且对表面形状的变化十分敏感。为了保证结构的安全性和经济性，在进行结构设计前进行适当的风洞实验是非常必要的。

| Abstract: | Taking the membrane structure roof of Hangzhou Swimming Stadium for example, wind load characters on large slope roof were studied by wind tunnel simulation. It is shown that there are certain patterns of wind pressure distributions on this kind of roof, which are sensitive to the change of wind direction. In order to achieve the safe and economic goal, the wind tunnel tests are strongly recommended and necessary before the design of memberane structure. |
