摘　　要：杭州黄龙体育中心网球馆屋盖属于可开启结构,部分屋盖可沿平行轨道滑动,结合该主体结构的抗风设计要求制作1∶100的刚性模型,进行了结构表面平均风压和脉动风压分布的风洞试验.分析了在不同风向角时关闭和开启屋盖状况下的风压分布.为了便于结构设计,根据实际情况对屋面进行分区并给出相应的分区风压数据,并依据各风向角下的风压分布特征,得出整体结构的抗风设计依据值.The roof of Hangzhou Huanglong Tennis Gymnasium is retractable. Part of the roof can slide along two parallel tram roads. For the requirements of wind resistance design for the structure, a rigid model with scale was made, and the wind tunnel test about pulsating wind pressure and mean wind pressure on the structure surface was carried out. The distribution of wind pressure on the ellipsoidal surface roof including retractable roof at different wind direction and under all kinds of work conditions including open, semi-open and close is examined. To facilitate structure design, the roof is divided into several regions, based on the structure characteristics and corresponding regional wind pressure is offered. Finally, based on the characteristics of the distribution of wind pressure at different wind directions, the most dangerous wind directions for the structural Wind resistance are also presented.
