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度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
Taking the roof of Hangzhou Natatorium membrane as an example, the wind load characteristics of the roof structure with large gradient are studied by wind tunnel simulation experiment. The results show that the wind load characteristics of such structures have certain regularity and are sensitive to the change of surface shape. In order to ensure the safety and economy of the structure, it is necessary to conduct proper wind tunnel experiment before structural design
