Abstract: The method and result for the fluctuating pressure wind tunnel test of the Macao Handover CeremonyHall are introduced, and the distribution characteristics of fluctuating pressure on the wall and roof surfaces and its influential factors are analyzed. The experimental results showthat 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 ismarkedly disturbed bynearbybuildings. 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 thatwhich door is open.
