Excerpt from A Study of Wind Pressures on a Single-Family Dwelling in Model and Full ScaleWind pressures measured on a single-family dwelling are compared with results obtained from a scale model placed in a turbulent boundary layer. It is shown that the fluctuat ing components of surface pressures far exceed the mean or steady pressures and are well correlated over sizeable roof areas. The consistently low fluctuating pressure coefficients obtained from the wind tunnel model are attributed to improper simulation of the lower portion of the atmospheric boundary layer. Comparisons between actual loads and Specified design loads suggest that certain current provisions are marginal for tributary areas and excessive for localized areas such as ridges, eaves and corners. A procedure for expressing loads on both localized and extended roof areas in terms of mean pressure coefficients and a peak factor is described.Key words: Aerodynamics, boundary layers, buildings, codes and standards, wind loads, wind tunnels.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
