Embracing Eurocode 5 (EC5) (Version 2)

TRADA image

April 1st 2010 marked the theoretical end of three years' co-existence of British National structural design standards and the Eurocodes. In fact, the British Standards Institute (BSI) withdrew much of BS 5268 structural use of timber in November 2009, four months earlier than the industry expected. The Department of Communities and Local Government (DCLG), which produces the Building Regulations for England and Wales, announced in December 2009 that the Approved Document A - Structure (last amended in 2004) is unlikely to be amended again before 2013, despite its reference to the obsolete National standards.

This Construction Briefing addresses the need for the timber industry to accelerate its migration to Eurocode 5 Design of timber structures (EC5). It summarises the consequences of moving to EC5 and highlights the importance of rapidly completing this grand undertaking.

Embracing Eurocode 5 is TRADA's second Construction Briefing and it deals primarily with the reasons behind and the implications of implementing EC5 in the UK before drawing several conclusions on how the timber industry should proceed with putting EC5 into practice.
