Summary

Communities and Local Government commissioned this calibration study. The study focused on the key parameters that will have a significant effect on design wind loads on structures. The issues that have been studied are comparison of:

• wind speeds at the centre of 10kM inland squares and at the centres of 10kM coastal segments
• wind pressures for sites in country and in town when orography is not significant
• wind pressures for sites in country and in town when orography is significant
• overall loads on typical building types in seven sites across the UK
• altitude factors and dynamic magnification factors
• external pressure coefficients for walls and roofs and comparison of cladding loads for typical building types in seven sites across the UK
• size effect factors

In each case the results of the procedures given in BSEN 1991-1-4 and its UK draft National Annex and those obtained by using BS 6399 Part 2 are compared.
