The UK National Annex to BS EN 1991-1-4, BS EN 1991-1-5, and PD 6688-1-4

The objective of this paper is to give the background to the development of the National Annexes to BS EN 1991-1-4: 2005[19], BS EN 1991-1-5: 2003[20] and Published Document PD 6688-1-4: 2009[21], focussing particularly on those aspects which relate to the design of bridges. The relevant clauses in the Eurocodes have been reviewed, comparing them against clauses in the UK bridges standard BS 5400[22] and any other relevant British Standards.
