Full scale pressure measurements at the Texas Tech Field Research Laboratory have been used to investigate the distribution and correlation of fluctuating pressures on a low rise building. Eigenvector analysis of the covariances indicate that longitudinal and lateral turbulence are responsible for the majority of pressure fluctuations. However, a significant second eigenvector for flow normal to the roof edges corresponds with the rollup and discrete shedding of the separation bubble as a whole. Conditional sampling of peak pressures shows that they are better correlated spatially than the time averaged fluctuations. © 1993.
