| 摘 要： | 对一座将建于强风区的悬挑屋盖(雨篷)结构模型进行了风洞试验，研究了大跨度悬挑屋盖上的风荷载特性。不同工况下屋盖表面的风压分布特性表明，周边建筑对所测建筑的风荷载有较大的干扰影响。还研究了在顶部开洞情况下屋盖表面的风压分布特性，结果表明开洞后屋盖上的风压有一定程度的降低。

| Abstract: | In this paper,a wind tunnel test of a large span cantilever roof model is carried out in TJ-2 Boundary Layer Wind Tunnel to investigate the wind loads on the roof. The characteristics of wind pressure distributions at different work conditions show that the neighboring buildings have significant aerodynamic interference effects. In addition,the characteristics of wind pressure distributions on the roof with the openings at the top are studied,which indicates that the wind loads on the roof reduce to some extents with the openings. |
