在两高层建筑的影响下,受绕的大跨屋盖结构屋顶表面风压分布较孤立状态下有较大变化。试验通过改变施绕建筑与受绕建筑间的相对位置以及变化风向角,分析得出各个工况下屋盖顶面的风压系数,绘成等值线图。本文分别比较了沿横风向施绕建筑间净距的改变和沿顺风向施绕建筑与受绕建筑间净距的改变时,各工况的风压分布等值线图,研究了大跨结构屋盖顶面风压变化情况,从而得出了一些方形高层建筑对大跨屋盖结构的静风干扰效应的结论。 Under the influence of two high-rise buildings, the wind pressure distribution on roof surface of long-span roof structure underwent a great change compared with the isolated state. Through changing the relative position between the building and the surrounding building and changing the wind direction angle, the wind pressure coefficient of the top of the roof under each working condition was analyzed and the contour map was drawn. In this paper, we compare the wind pressure distribution contour map of wind pressure distribution along the crosswind wind direction and the change of the windage distance between the windward and surrounding buildings, Roof top wind pressure changes, which draws a number of square high-rise buildings on the long-span roof structure of static wind interference effect conclusion.
