［摘要］基于SST k-ω湍流模型封闭求解N-S方程的RANS方法，模拟了CAARC高层建筑标准模型的风压，在验证数值方法具有较好精度的基础上，模拟计算几种典型平面布局的高层建筑群风压场，通过对各布局建筑物风压分布及风力的比较，获得平面布局对风压分布影响的规律，可为建筑布局规划及抗风设计提供参考和评价依据。

Numerical research of layout effect on wind pressure of high-rise buildings complex

Wang Hui(School of Civil Engineering, Hefei University of Technology, Hefei 230009, China)

Abstract:Based on Reynolds-averaged N-S equations, in which SST k-ω turbulence model was used, the wind pressure on CAARC standard high-rise building model was numerically simulated. The satisfactory agreement between the computational results and wind-tunnel test results indicates that the numerical simulation is an effective tool to study the wind pressure on high-rise buildings.  Wind pressures on high-rise buildings complex which have some typical layouts were simulated. The wind pressure and wind forces on the buildings were compared and analyzed in order to get laws of layout effects on wind pressure distribution. The acquired laws can be reference for layout planning and wind-resistant design of buildings.

Keywords:high-rise buildings complex; layout; wind pressure; aerodynamic interference; numerical simulation
