Worst suctions near edges of flat rooftops with parapets
AbstractAn earlier paper considered inconsistencies between suction data published by different authors for flat rooftops on low-rise buildings. The present paper reviews new data which support the conclusions of the earlier paper and permit them to be extended to intermediate and high-rise building stages.Pressure patterns and worst suction values are found to be much the same for low, intermediate and high-rise building shapes and occur over small regions very close to the edges of the roofs. Worst suctions are found to be substantially higher than values previously reported by some researchers. A very high density of pressure taps is required to capture the suction peaks in wind tunnel experiments. Some previous experiments appear to have been deficient in this respect. Worst suctions decrease monotonically with increasing parapet height; data are presented for low-, intermediate- and high-rise building shapes.
