| 摘 要： | 通过风洞模拟试验研究了椭球形舞台壳体 ,及其三种开启状态时的风荷载特性。结果表明就整体风荷载而言椭球体的阻力系数不是很大 ,但由于气流的分离和再附 ,椭球体的局部会出现很大的负压 ,系数可达 2 .0以上。另外 ,周围建筑对椭球形舞台壳体的风荷载影响很大。

| Abstract: | By means of wind tunnel test the wind loading on a stage with a shape of elliptical sphere was carried out. The results show that the total drag force is not so big, however, because of the flow separation and reattachment, large suction force will occur on the local surface area of the shell. The largest pressure coefficients may over 2.0. On the other hand, the structures around stage have great effects on the wind loading on the stage. |
