Roof corner wind loads and parapet configurations

Effect of roof-edge parapets on mitigating extreme roof suctions

“…Several geometric modifications that have been considered by previous investigators (Banks, 2000;Baskaran and Stathopoulos, 1988;Kopp et al, 2005;Stathopoulos and Baskaran, 1988;Surry and Lin, 1995;Wu, 2000) to reduce the corner suction pressures are discussed below.…”

Wind tunnel study on the influence of different parapets on the roof pressure distribution of low-rise buildings

“…The use of vertical parapets located at the roofs edges has been studied in the past in order to reduce the high suction caused by the conical vortices [5][6][7][8][9]. As far as we know, most of the studies devoted to the effect of parapets on roof suction loads are dealing with solid parapets, and none or little effort has been dedicated to porous parapets.…”

06/01832 A parametric, experimental analysis of conical vortices on curved roofs of low-rise buildings

“…Concerning flat roofs, in addition to some analytical and numerical approximations [1], the study of the accurate nature of conical vortices has been mainly performed through experimental work made on wind-tunnel models [2][3][4][5][6][7][8][9][10] and through measurements made on full-scale buildings [11][12][13]. In the case of flat roofs, the use of parapets, either solid [14][15][16][17] or porous [18], to reduce the high suction caused by conical vortices has been studied. Some attempts have been made to analyse conicalvortex effects on curved roofs, either with parapets [19] or without these devices [20], although in this case results are scarce and limited to some particular roof geometries.…”
