To make sure the standard is up-to-date with technical and social developments, the British Standards Institution (BSI) has published a revision to BS 5400-2:1978 Steel, concrete and composite bridges. Specification for loads.
This standard has been updated in the following areas:
The UK wind map
The effect of terrain roughness on the properties of the wind
The effect of fetch of particular terrains on the properties of the wind
The effects of topography on the properties of the wind
The treatment of pressure coefficients (drag and lift)
The treatment of relieving areas
Highway/railway bridge loading
Clauses on thermal actions
NEW EDITION - BS 5400-2:2006
Steel, concrete and composite bridges. Specification for loads
BS 5400-2:2006 supersedes BS 5400-2:1978 which is now withdrawn. However this new edition does not reflect a full review or revision of the standard. Its primary purpose is to keep it in line with revisions to other related standards and the Highways Agency standard BD 37/01, pending the introduction of the structural Eurocodes.
