椭球面屋盖与圆锥面玻璃幕墙的风压分布特征

Wind Pressure Characteristics of Ellipsoidal Surface Roof and Conical Surface Glass Gladding

结合杭州大剧院主体结构风压分布的风洞试验研究 ,详细介绍了风洞试验及数据处理方法 ,讨论了在不同风向角下椭球面屋盖和圆锥面玻璃幕墙的风压分布 ,并与荷载规范中类似结构的风压分布进行了比较。为了便于整体结构设计 ,根据结构的实际情况对椭球面和圆锥面进行分块并给出相应的分块风压数据 ,根据各风向角下的风压分布特征给出了整体结构抗风设计的最不利风向角。

Based on the wind tunnel test of wind pressure distribution on Hangzhou Grand Theater,the methods of the wind tunnel test and data processing are introduced in detail,and the distribution of wind pressure of the ellipsoidal surface roof and the conical surface glass gladding at different wind directions are discussed.The experimental results are also compared with the distribution of wind pressure of similar structure on the load code.In order to facilitate structure design,the ellipsoidal surface and the conical surface are divided into several regions based on the structure characteristics and corresponding regional wind pressure is offered.Based on the characteristics of the distribution of wind pressure at different wind directions,the most dangerous wind directions for structural wind resistance design are offered.
