This is the third part of a three-part Digest giving guidance on the use of Eurocode 1 (BS EN 1991-1-4). This Digest is aimed at engineers, architects and other professionals who need to understand how to calculate the effect of wind on buildings and design options to minimise it. Wind loads on bridges are not covered in this Digest.
Part 3 of this Digest demonstrates the calculation procedure for determining wind loads using the full dynamic method from Annex B of BS EN 1991-1-4. It includes an example calculation for determining the dynamic response of a 128 m tall building (referred to as ‘Example 3’ to differentiate from the examples referred to in Part 2).
Part 1 gives advice and guidance on the use of
BS EN 1991-1-4 and Part 2 demonstrates the calculation procedure for determining wind loads and includes example calculations for a two-storey house and a 120 m tall tower on a two-storey podium. This update to Part 3 replaces the guidance published in 1999.
In this Digest we will refer to BS EN 1991-1-4 as the ‘EN’, the UK National Annex to BS EN 1991-1-4 as the ‘NA’ and PD 6688-1-4 as the ‘PD’.
