Full-scale wind load measurements point the way forward

Refinement of experimental technique has enabled more detailed analyses to be made of the full-scale measurements on the Silsoe Structures Building. This has shown the relevance of quasi-steady analysis in assessing rms and maximum and minimum pressure coefficients, and highlighted the effect of turbulence averaging on the mean pressure coefficient. Comparisons of the spectra of the approaching turbulent flow and of the surface pressure indicate the changing patterns that occur as the flow develops over the building. The results of the quasi-steady analysis have direct implications on wind tunnel modelling.
