[摘要] 结合扬中奥体体育场项目，通过对26m跨度悬挑屋盖结构进行风洞试验，并利用结构有限元模型进行平均风荷载计算及随机风振响应时程分析，确定结构各部分的体型系数、基本风压、风振系数等，为结构设计提供合理、可靠的风荷载数据。

Abstract: Combined with construction project of Yangzhong Olympic Stadium, a wind tunnel experiment was carried out as to a 26-meters-long cantilevered-roof. And wind load calculation and stochastic wind vibration response analysis were aclueved with the help of FEM analysis. Shape factor of wind load of the cantilevered-roof, basic wind pressure, and wind vibration faction were analyzed to provide reasonable and reliable wind load data for structure design.
Keywords: cantilevered roof; wind tunnel experiment; wind vibration factor
