Extreme-value analysis for observed peak pressures on the Silsoe cube

Abstract

The application of the type III extreme-value distribution to wind engineering problems is discussed critically. Recent studies of aerodynamic coefficients from wind tunnel experiments show that the extremes of some local pressures and some global forces follow a type III distribution. The actual study therefore intends to investigate if a type III distribution can be fitted to the full-scale data from the 6 m Silsoe cube. Since the independent runs may vary with the mean wind speed, adjustments to the data become necessary to ensure that the sampled peaks from different runs can be compared.
