Bridge Design Provisions of UK NA for EN 1991-1-7 AND PD 6688-1-7

BS EN 1991-1-7 was published in 2006 to provide the requirements due to accidental actions on bridges. The UK National Annex to BS EN 1991-1-7 and the associated UK Publication Document PD 6688-1-7 were both published in 2008.

The preparations of UK National Annex and Publication Document were undertaken by Mouchel, Flint and Neill and Parsons Brinckerhoff for the Highways Agency and by RSSB.

This paper describes the background to the development of the NA and PD that support BS EN 1991-1-7.
