Part 7 deals with the assessment of more frequent parent wind speeds in the UK from the extreme wind speeds given by Part 3.

Two procedures are given:                                                                                         

•    for estimating the number of occurrences of  wind speeds for making fatigue assessments.

  for estimating the values of wind speeds occurring for between one and one hundred hours per year, for making serviceability assessments     

The procedure for serviceability assessments is based on the approach used in BS8100

Lattice towers and masts augmented with new data and further refined since publication of BS 8100. The procedure for fatigue assessments is based on analysis of extreme meteorological and loading data in the UK, but gives very similar results to the procedure in ECCS Recommendations for calculating the effects of wind on constructions.
