方形高层建筑横风向层风力干扰特性

Characteristics of Across wind Layer Wind Force Interference Effect of Two Square Tall Buildings

摘要:

利用刚性模型测压试验研究受扰建筑层风力的干扰特性，研究了施扰建筑在不同位置时受扰建筑的横风向层风力沿高分布情况以及其干扰因子沿高分布情况，给出了并列和串列时的脉动层风力系数沿高分布拟合公式.结果显示，施扰建筑可能会使受扰建筑横风向平均层风力不再为零，横风向脉动层风力沿高分布情况及其干扰因子沿高分布情况与施扰建筑位置关系密切，脉动层风力干扰因子最大可达2.26.

Abstract:

Layer wind force interference characteristic of disturbed building is studied by rigid model pressure test, and this paper presents the across wind layer wind force interference characteristic. Distribution of across wind layer wind force and its interference factors with interfering building arranged in different position is considered, fitting formulas describing the characteristic of across wind root mean square(RMS) layer wind force coefficients for side by side and tandem arrangement are obtained. The results show that interfering building probably leads to the across wind mean layer force’s deviation from zero, across wind RMS layer force interference factors can reach up to 2.26.
