NUMERICAL SIMULATION OF STATIC INTERFERENCE EFFECTS FOR SINGLE BUILDINGS GROUP

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.
