［摘要］東營會展中心展館屋蓋為一大跨度圓柱殼空間曲面，周邊懸挑較多，考慮到該建筑的重要性及膜結(jié)構(gòu)對風(fēng)荷載的敏感性，利用縮尺模型風(fēng)洞試驗對展館屋蓋在各種風(fēng)向角下的風(fēng)壓分布情況進(jìn)行了測試，得出了風(fēng)荷載壓力系數(shù)等參數(shù)，為展館的抗風(fēng)設(shè)計提供了可靠的依據(jù)。

Abstract: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.
Keywords:cylindrical shell roof; wind tunnel test; average wind pressure coefficient; fluctuating pressure coefficient
