THE SILSOE-STRUCTURES-BUILDING - COMPARISON OF 1 100 MODEL-SCALE DATAWITH FULL-SCALE DATA/

Model-scale data for the Silsoe Structures Building, from the BRE Boun dary Layer Wind Tunnel number 3, is compared to recent full-scale data . Assessment of boundary layer simulation precedes a comparison of sur face pressure measurements. For transverse winds both sets of data com pare well. Model-scale measurements underestimate the mean pressure co efficient for cornering winds. This is exemplified by data for one tap ping point at the gable end of the roof. For this tap, the quasi-stead y assumption is shown to apply to the reference dynamic pressure spect rum.
