Developments in Integral Bridge Design

The Eurocodes do not cover important aspects of the design of integral bridges, including the behaviour of soil behind bridge abutments that is subject to repeat thermal movement. PD 6694-1[1] therefore contains recommendations and guidance for the design of integral bridges. These update the UK recommendations for integral bridge design contained in BA 42/96[2] in the light of recent research and to align them with the Eurocode design philosophy. This paper explains their background.
