摘 要：The aerodynamic performance of a roof depends significantly on its shape and size,among other *** instance,large roofs of industrial low-rise buildings may behave differently compared to those of residential *** main objective of this study is to experimentally investigate how perimeter solid parapets can alter the flow pattern around a low-rise building with a large aspect ratio of width/height of about 7.6,the case of industrial buildings/shopping *** parapets of varied sizes are added to the roof and tested in an open-jet simulator in a comparative study to understand their impact on roof pressure *** pressures were measured in the laboratory for cases with and without parapets under different wind direction angles(representative of straight-line winds under open terrain conditions).The results show that using a parapet can alter wind pressures on large *** can modify the flow pattern around buildings and change the mean and peak *** mean pressure pattern shows a reduction in the length of the separation bubble due to the *** parapet of 14%of the building’s roof height is the most efficient at reducing mean and peak pressures compared to other parapet heights.
