摘要
基于流体动力学软件CFX10.0计算平台,采用数值模拟方法对行列式群体建筑物间的相互干扰效应进行模拟,研究各单体建筑表面的风荷载平均风压系数干扰因子随建筑物间距Sx的变化规律,得出当Sx较小时,变化规律复杂,上游建筑对下游建筑呈现明显的遮挡效应,当Sx大于3b时,建筑群中各个建筑表面干扰因子趋于稳定。从风干扰角度为中高层建筑群的设计提供参考。
The numerical simulation method was adopted to study the interference effect of the matrix buildings based on the platform of Computational Fluid Dynamics software CFX10. 0. The interference factor of the average wind pressure coefficient of buildings' surfaces with the variable Sx was deduced out. It shows that the variation is more complex when Sx is on the small side,but it will stabilize as Sx is more than 3b. Upstream building showed significant shielding effects on the downstream buildings. This article could provide reference to the design of mid-high-rise buildings.
