摘　　要：东营会展中心展馆屋盖为一大跨度圆柱壳空间曲面,周边悬挑较多,考虑到该建筑的重要性及膜结构对风荷载的敏感性,利用缩尺模型风洞试验对展馆屋盖在各种风向角下的风压分布情况进行了测试,得出了风荷载压力系数等参数,为展馆的抗风设计提供了可靠的依据。The roof of the gallery is tested with the wind from various directions angles through reduced-scale wind tunnel test. The test is made due to the fact that the roof is a cylindrical shell surface spaces and there are many cantilevers around, the importance of the structure and the sensitivity of the membrane to the wind loading are also considered at the same time. This test obtained some important parameters such as the average wind pressure coefficient which provides the wind-resistant design with the reliable basis.

关 键 词：圆柱壳屋盖 风洞试验 平均风压系数 脉动压力系数
