摘　　要：以灌南体育场、浦江体育场、金华体育场的罩棚结构为工程背景,基于刚性模型表面测压风洞试验结果,得到了罩棚结构表面各测点的风压时程,并总结了挑棚结构风压分布的一般共性特点及由于结构形式的不同对风压场分布的影响,得出悬挑屋盖挑蓬前缘拱可以明显改善屋盖结构抗风性能的结论。Taking the awning structure of Guannan stadium, Pujiang stadium, Jinhua stadium as the engineering background, based on wind pressure tunnel experimental results of rigid surface model, obtained the wind pressure time history of surface each measuring point of awning structure, and summarized the general common characteristics of wind pressure distribution of overhanging roof structure, and because of the in-fluence of different structure to wind pressure distribution, drew the conclusion of cantilevered roof awning front arch could significantly improve the wind resistance performance of roof structure.
