Background

• Eurocodes have been in development since mid 1970s• Suite of ‘pre-standards’ (BS ENV) introduced in 1990s• Pre-standards replaced by ‘Euro-Norm’ standards (BS EN)

• Conflicting Standards withdrawn in most CEN member countries in March 2010

Seminar ‘Bridge Design with Eurocodes’ – JRC Ispra, 1-2 October 2012 49

Key Eurocode requirements

Models / idealisations used for analysis

Should be appropriate to the problem / limit state / stage of construction being considered

Should reflect behaviour with appropriate accuracy

Should be consistent with design assumptions

Concrete EN1992

Should be based on established engineering theory and practice, & if necessary, verified experimentally
