单列建筑群静力干扰效应的数值模拟

NUMERICAL SIMULATION OF STATIC INTERFERENCE EFFECTS FOR SINGLE BUILDINGS GROUP

  • 摘要: 采用CFD数值模拟技术,对处于C类地貌风场中由3栋建筑形成的单列建筑群进行静力风荷载和风场的数值模拟. 数值模拟采用良好适应性的非结构化四面体单元进行网格划分,侧重模拟分析了各风向角下建筑间距的改变引起面平均风压系数的改变,由此得到了此类群体建筑表面风压系数干扰因子在各风向角下随建筑间距变化的分布规律和特征.

     

    Abstract: In wind field of category C ground feature, numericalsimulation of static wind load and wind field were performed for singlebuildings group composed of three buildings by CFD. Tetrahedron discretegrid with good adaptability has be adopted in this paper. The wind pressurecoefficient in various spacings at any wind angle are simulated andanalyzed. Distribution laws and characteristics of wind pressure coefficientinterference factor on this kind of building surface following the change ofspacing at any wind angle have been obtained. The result of numericalsimulation could provide basis for building groups distribution optimizationand wind-resistant design of structures.
