Loadings - British Standards

The main Standard for loadings applied to structures was BS 6399 in three parts. These, like many of the structural codes, have been replaced by European Standards.

BS 6399-1: ´Code of practice for dead and imposed loads´ this gives dead and minimum imposed loads, applicable to new buildings, alterations to existing structures and existing structures on change of use. Replaced by BS EN 1991-1-1 & BS EN 1991-1-7

BS 6399-2: ´Code of practice for wind loads´, Replaced by BS EN 1991-1-4

BS 6399-3:´Code of practice for imposed roof loads´. For use in designing buildings and building components that are to be constructed and used in the UK and Channel Islands. Replaced by BS EN 1991-1-3

Loadings for bridges (for highways, railways and foot/cycle tracks) are covered by BS 5400: ´Steel, concrete and composite bridges´,Part 2: ´Specification for loads´ and National Highways . Again, the BS 5400 was replaced by BS EN 1992-2 and in November 2023 was incorporated into BS EN 1992-1-1:2023

Special structures will have their own loading requirements.
