Wind tunnel measurements of cavity pressure dynamics in a low-rise flexible roofed building

摘要

Results are presented from a series of wind tunnel tests to measure the cavity pressure dynamics of a flexible roofed building with a single dominant opening. Tests were conducted in a simulated atmospheric boundary layer, representative of an open-country terrain, for the model configured with five different roof tensions, three internal volumes, two windspeeds and five opening azimuth angles. The ratio of air-to-building bulk moduli was used as a measure of roof tension and buildings with 0.02
