Effect of eaves detail on wind pressures over an industrial building

Abstract

Results of full-scale wind pressure measurements on the Silsoe Structures Building are presented that reveal the effect on wind loadings of a modern curved eaves cladding detail as compared with a traditional sharp line (gutter) eaves. It is shown that the loading distribution is affected over the majority of the roof span — beneficially near the windward eaves but detrimentally over the ridge. Flow visualization studies together with coefficients of turbulence intensity provide good evidence of the differences between the flow regimes developed by the two eaves arrangements.
