Abstract
Point and area-averaged pressures are presented for enclosed low rise (height ( h)/breadth (b) = 1 3 building roof, based on 1:100 scale wind tunnel measurements obtained in a simulated suburban atmospheric surface layer. Large magnitude mean and peak suction pressures were measured close to the leading edges under the separating shear layer. Significantly larger magnitude mean and peak pressures were measured on 0.2 h (wide) by 1.0 h (long) rectangular edge strips compared to the pressures on 1.5 h by 1.0 h roof sections. Pressure factors of the order of 3.0 for suction pressures were obtained for these regions which are larger than code values. However, measured peak area-averaged suction pressures were significantly smaller than code values.
