［提要］介紹了武漢體育中心體育館風(fēng)洞試驗(yàn)?zāi)M方法和試驗(yàn)結(jié)果，討論了不同風(fēng)向角下屋蓋表面風(fēng)壓的分布，并得出風(fēng)荷載的分布規(guī)律。在考慮了上游有建筑物影響的情況后，分析了周圍建筑對(duì)屋蓋表面風(fēng)壓的干擾效應(yīng)。圍護(hù)結(jié)構(gòu)的設(shè)計(jì)風(fēng)壓分別由我國(guó)規(guī)范和基于隨機(jī)振動(dòng)理論的標(biāo)準(zhǔn)方法計(jì)算所得，通過(guò)兩種方法的比較，得到了若干結(jié)論。

Wind Tunnel Test for Wind Pressure on Gymnasium of Wuhan Sport Center/Yu Xiulei¹，Liang Shuguo¹，Guo Biwu²（1  School of Civil Engineering,Wuhan University, Wuhan 430072,China； 2 Wuhan Institute of Architectural Design，Wuhan 430014,China）

Abstract:The approach and main results of the wind tunnel test of the gymnasium of Wuhan sport center are introduced. Wind pressure distributions of roof in different wind directions are analyzed and the contour curves of mean wind pressures on the roof are obtained.In the meantime, the interference effects of the surrounding buildings on the roof are analyzed. The designed wind pressure of building is presented by the code method and statistical method based on random vibration theory respectively. By comparison of the results presented by these two methods, some conclusions are obtained.

Keywords:wind tunnel test; long-span roof; wind pressure on roof
