Abstract
Compatible with the proposed new British Standard BS 6399: Part 2. Deals with the assessment of more frequent parent wind speeds in the United Kingdom from the extreme wind speeds given by Part 3. Two procedures are given: i) for estimating the values of wind speeds occurring for between one and one hundred hours per year, for making serviceability assessments. ii) for estimating the number of occurrences of wind speeds for making fatigue assessments. The procedure for serviceability assessments is based on the approach used in BS 8100 Lattice towers and masts which has been augmented with new data and has been 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.
