［提要］ 通过风洞测压试验分析了深圳市民中心屋盖的平均风压和极值风压分布。试验表明，翘曲屋盖与平屋盖在风荷载特性上具有一定的类似特性，屋盖承受风荷载的最不利位置在斜角迎风区域，这主要是由于风遇屋盖分离形成的锥形漩涡所致。在法向迎风面形成的柱形涡也导致了较大的局部负压和升力，值得注意。

Abstract:The average and peak wind pressure distribution is analyzed based on
wind tunnel test.The results show that warp longspan roof is similar to flat roof in some degree when they are acted by wind loads. The most dangerous part of the roof under wind effect is the windward region when wind blows from 45°,which is caused by conical vortices generated by the separation of air current. On the other hand, cylindrical vortices cause fairly large wind pressure.
Keywords:longspan roof; cantilevered structure; warp roof; wind tunnel test
