EXPERIMENTAL RESEARCH ON WIND TUNEL PRESSURE MEASUREMENT OF A SUPER HIGH-RISE BUILDING

The distribution of wind pressure on the surface of super high-rise buildings has an important impact on the safe use of building envelopes. According to the wind tunnel pressure measurement experiment of a rigid model of a super high-rise building, this paper introduces the method of wind tunnel test in detail, and investigates the changing law of wind pressure under different wind direction angles. The results show that when the incoming wind direction is perpendicular to the plane, the measuring point on the plane has the maximum positive pressure; When the incoming wind direction is parallel to the plane, the measuring point on the plane often has the largest negative pressure. The wind pressure has a great influence, but the distribution trend of wind pressure remains unchanged; the difference is that it will amplify the local wind pressure, especially in the middle of the building. This study gives some suggestions for the structural design of super-high rise buildings.
