［摘要］上海浦東足球場為跨度211m的輪輻式張弦結(jié)構(gòu)體系，對其屋蓋風荷載進行了研究。首先，通過1/300縮尺比的同步多點剛性模型測壓風洞試驗獲得了屋蓋上下表面的風平均內(nèi)壓和風壓系數(shù)； 其次，由風洞試驗結(jié)果分析得到24個風向角下100年重現(xiàn)期對應(yīng)的屋蓋表面的風峰值外壓； 最后，結(jié)合結(jié)構(gòu)的動力特性以及風洞試驗結(jié)果計算了結(jié)構(gòu)的風振響應(yīng)和等效靜力風荷載。結(jié)果表明：屋蓋平均內(nèi)壓分布均勻并且隨風向角變化不大； 在迎風面外邊緣可能出現(xiàn)最大的峰值外壓； 屋蓋整體結(jié)構(gòu)沿豎向的平均氣動力和等效靜力風荷載隨風向角的變化有相似的變化趨勢。

Abstract:Shanghai Pudong Football Field is a 211m-span spoke string structural system. The wind load on the roof was studied. Firstly, the wind tunnel test of 1/300 scale synchronous multi-point rigid model was carried out to obtain the average wind pressure and wind pressure coefficient of the upper and lower surfaces of the roof; secondly, the peak external pressure of the roof surface corresponding to the 100 year return period under 24 wind directions was obtained by analyzing the wind tunnel test results; finally, the wind-induced vibration response and the static wind load of the structure were calculated based on the dynamic characteristics of the structure and the wind tunnel test results. The results show that the average internal pressure distribution of the roof is uniform and does not change with the wind direction angle; the maximum peak external pressure may appear at the outer edge of the windward surface; the average aerodynamic force and equivalent static wind load of the whole roof structure along the vertical direction have similar change trend with the change of wind direction angle.
Keywords:large-span roof structure; Shanghai Pudong Football Field; wind tunnel test; wind-induced response analysis
