澳门政权交接仪式场馆脉动风压风洞试验

介绍了澳门政权交接仪式场馆脉动风压风洞试验的方法及结果，分析了外墙表面及屋面脉动风压分布的特点和影响因素．试验结果表明：该大型场馆屋面上表面主要分布为负压，悬挑边缘迎风时负压较大，风压分布受周围建筑干扰严重；屋面下表面与外墙的风压分布类似；内压的大小与开门方向、风向角有很大关系。

Experimental Investigation of Fluctuating Pressure on Macao Handover Ceremony Hall

The method and result for the fluctuating pressure wind tunnel test of the Macao Handover Ceremony Hall are introduced, and the distribution characteristics of fluctuating pressure on the wall and roof surfaces and its influential factors are analyzed. The experimental results show that the upper surface of the hall's roof is mainly loaded by suction, it is comparatively big on cantilevered edges, and the regularity of pressure distribution is markedly disturbed by nearby buildings. The distribution of fluctuating pressure on the lower surface of the hall's roof is similar to that of fluctuating pressure on the wall surfaces. The inner pressure is largely related to the wind directions and the fact that which door is open.
