EFFECTS OF GEOMETRIC PARAMETERS ON MEAN WIND PRESSURE ON GABLE ROOFS OF LOW-RISE BUILDINGS

A series of pressure measurement wind tunnel tests were carried out on low-rise buildings in a simulated suburban wind field.The effects of roof pitch, height/breadth ratio and depth/breadth ratio of gable-roofed low-rise buildings on mean wind pressure coefficients on their roofs for winds parallel or perpendicular to the ridges were discussed.Two new equations of mean wind pressure coefficients, which may be useful for design purpose, were fitted with the test data for various building shapes and the errors of those equations were analyzed carefully.The calculated results with the equations were compared with present wind tunnel test data and literature in detail.
