某超高层建筑表面风压分布研究

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

  • 摘要: 超高层建筑表面的风压分布对建筑表面围护结构的安全使用有重要影响。据某超高层建筑的刚性模型风洞测压试验,研究了超高层建筑周围在有、无干扰建筑的情况下,表面的风压分布特性以及一些特殊测点在不同风向角的情况下风压的变化规律。结果表明:当来流风向与平面垂直时,平面上的测点取到最大正压,当来流风向与平面平行时,平面上测点往往负压最大;环境建筑对该高层建筑侧风面的风压影响较大,但风压的分布趋势不变,不同在于会放大局部风压,尤其是建筑中部。为其结构设计提出一些建议。

     

    Abstract: 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.
