以杭州网球馆两种不同形状的膜顶结构为例 ,通过风洞模拟试验说明膜顶形状的改变对其风荷载的敏感性及其影响。说明了在进行初步设计阶段对这类轻型结构进行风洞模拟试验的必要性。详细分析了这类结构屋顶的表面风压分布随风向角变化的规律。
Taking Hangzhou Tennis Hall two different shapes of membrane roof structure as an example, the wind tunnel simulation experiment shows that the change of the shape of the membrane top is sensitive to the wind load and its influence. The necessity of wind tunnel simulation test for such light structures during the preliminary design stage is illustrated. The regularity of surface wind pressure distribution with the change of wind direction angle is analyzed in detail.
