WIND ENVIRONMENTAL-CONDITIONS AROUND TALL BUILDINGS WITH CHAMFERED CORNERS

An experimental investigation of ground-level wind conditions around buildings with chamfered corners has been carried out. Experiments included models of both square and chamfered buildings of various heights ranging between 60 and 180 m exposed to a simulated open country terrain. Results indicate that chamfering a corner of a tall square building at 45 degree to its original faces may significantly reduce the size of strong wind area in the corner stream. This reduction is more pronounced for taller buildings and occurs for normal and oblique wind directions as well. J. Gandemer's comfort parameters, including some effect of turbulence, give results consistent with mean velocity ratios around buildings with chamfered corners.
