摘要
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。
Wind-tunnel simulations of wind loading on membrane structure roof of Hangzhou Tennis Stadium were carried out with two different shapes.The results show that the wind loads are important and sensitive with the shape change.It is believed that the wind tunnel simulations are necessary for the early stage of design.The detailed patterns of wind loading on the roofs with various wind directions are given and analyzed.
