| Abstract: | In wind field of category C ground feature, numerical
simulation of static wind load and wind field were performed for single
buildings group composed of three buildings by CFD. Tetrahedron discrete
grid with good adaptability has be adopted in this paper. The wind pressure
coefficient in various spacings at any wind angle are simulated and
analyzed. Distribution laws and characteristics of wind pressure coefficient
interference factor on this kind of building surface following the change of
spacing at any wind angle have been obtained. The result of numerical
simulation could provide basis for building groups distribution optimization
and wind-resistant design of structures. |
