摘　　要：通过对凤凰传媒中心刚性模型的风洞试验,分析研究了这种非大变形柔性的大跨屋盖结构的风压分布特性,得到了在不同风向角下外围壳体和中庭悬索膜结构表面的平均风压系数.结果表明:外围壳体的风压,除环形外侧主要正迎风面和环形内侧的小部分迎风面为正压外,大部分都为吸力;中庭悬索膜结构表面主要以吸力为主.Wind pressure distribution characteristics of the Phoenix Media Center flexible roof,in non-large deformation,were analyzed by wind tunnel tests of the rigid model.Meanwhile,the average wind pressure coefficients on the surfaces of the outer shell and the atrium with a suspended cable-membrane structure in different wind direction angles were obtained.It is shown that the wind effects of the majority of the outer shell are suction,except that positive wind pressure distributes on the main windward side of the outer shell and a small portion of the windward side of the insider shell,but the effects of wind pressure on the atrium with a suspended cable-membrane structure are mainly suction.
