NUMERICAL APPROACH FOR WIND LOADS PREDICTION ON BUILDINGS AND STRUCTURES

An investigation of the ability of numerical codes to predict wind loa ds on buildings and structures, using kappa-epsilon closure model for turbulence, has been undertaken at CSTB. We present in this paper four cases for which wind-tunnel measurements are available: Pressure coef ficients around a cube model and a house model in a simulated atmosphe ric boundary layer, drag and lift forces on a hoarding model and a bri dge section model, located in the CSTB climatic wind tunnel.
