［摘要］基于SST k-ω湍流模型封閉求解N-S方程的RANS方法，模擬了CAARC高層建筑標(biāo)準(zhǔn)模型的風(fēng)壓，在驗(yàn)證數(shù)值方法具有較好精度的基礎(chǔ)上，模擬計(jì)算幾種典型平面布局的高層建筑群風(fēng)壓場，通過對各布局建筑物風(fēng)壓分布及風(fēng)力的比較，獲得平面布局對風(fēng)壓分布影響的規(guī)律，可為建筑布局規(guī)劃及抗風(fēng)設(shè)計(jì)提供參考和評價(jià)依據(jù)。

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
