Wind loads on planar canopy roofs, Part 1: mean pressure distributions

Mean pressure distributions on planar canopy roofs are presented based on 1 : 100 scale wind tunnel measurements obtained in a simulated suburban atmospheric boundary layer. For a range of roof pitch angles and wind directions, point and area-averaged pressure measurements were obtained with the worst loads experienced adjacent to lines of flow separation. In this study, generally smaller wake or suction mean pressures were obtained when compared with the earlier studies of Gumley. These differences are attributed to the interference at separation by the canopy supports in Gumley's work, and the higher level of turbulence in the present study. © 1992.
