A detailed test of the wind pressure distribution of a tall residential building was carried out in a Boundary Layer Wind Tunnel. The wind pressure distributions on the building were investigated. The results have shown that the correlations of wind pressures on the concave surface are very high at the same height. For the design of the double cantilevered roof, the upper is controlled by negative wind pressure and the lower by positive wind pressure. The glass tailgate at the top of the building is also controlled by positive wind pressure. The wind pressure distributions of the building are changed more noticeably if the surrounding buildings and topography exist. Especially under the height of the disruptors, the change of fluctuating wind pressure is significant. The min peak wind pressure has an increase of 28% when the building is disturbed.
