Worst suctions near edges of flat rooftops on low-rise buildings
Abstract Some inconsistencies have been noted between the suction data published by different authors for flat rooftops of low-rise buildings. New experimental data, together with some of the earlier data, show that the worst suctions are only mildly sensitive to the characteristics of the approach-flow boundary layer and that with low parapets the true worst suctions occur very close to the edges of the roof. It is hypothesised that the true worst suctions were missed by some of the previous investigators due to a lack or scarcity of pressure taps sufficiently close to the roof edges of their model buildings. The region of worst suctions comprises only a very small fraction of the total roof area and its influence on structural loads is small; it is, however, important as regards wind damage to roof-cladding systems. The paper includes data for the high-suction region of flat rooftops on low-rise buildings in 45° oblique winds for a range of parapet heights.
