The silsoe structures building: Comparison of 1 : 100 model-scale data with full-scale data

Abstract

Model-scale data for the Silsoe Structures Building, from the BRE Boundary Layer Wind Tunnel number 3, is compared to recent full-scale data. Assessment of boundary layer simulation precedes a comparison of surface pressure measurements. For transverse winds both sets of data compare well. Model-scale measurements underestimate the mean pressure coefficient for cornering winds. This is exemplified by data for one tapping point at the gable end of the roof. For this tap, the quasi-steady assumption is shown to apply to the reference dynamic pressure spectrum.
