矩形建筑结构静风荷载的干扰效应研究

STUDY ON WIND-INDUCED MEAN INTERFERENCE EFFECTS BETWEEN TWO RECTANGLE BUILDINGS

在相邻建筑物的干扰下,受扰高层建筑的风荷载与其在孤立状态下相比会有较大的变化。采用测压刚性模型风洞试验研究了两个高层建筑间的静力干扰效应,得到了两个相同的矩形截面建筑在不同相对位置和不同风向角下受扰建筑各表面的风压系数变化规律。所得的这些结果对结构的抗风设计有较为重要的指导意义。

As the aerodynamic interference of neighboring buildings,wind loads on tall buildings are considerably different from those on isolated buildings.Based on the date of the modeling wind tunnel tests,pressure coefficient between two tall buildings are researched.It revealled properly the law of the changes in pressure coefficient by the location and the wind direction.The results given by the paper might be a significant guide to structural design.
