BRITISH STANDARD BS EN 1994-22005 Eurocode 4 Design of composite steel and concrete structures Part 2 General rules and rules for bridges The European Standard EN 1994-22005 has the status of a British Standard ICS 91.010.30; 91.080.10; 91.080.40; 93.040 Licensed Copy x x, University of Glamorgan, Sat Apr 28 161032 GMT0000 2007, Uncontrolled Copy, c BSI BS EN 1994-22005 This British Standard was published under the authority of the Standards Policy and Strategy Committee on 2 December 2005 BSI 2 December 2005 ISBN 0 580 46902 6 National foreword This British Standard is the official English language version of EN 1994-22005. It supersedes DD ENV 1994-22001 which is withdrawn. The structural Eurocodes are divided into packages by grouping Eurocodes for each of the main materials, concrete, steel, composite concrete and steel, timber, masonry and aluminium. This is to enable a common date of withdrawal DOW for all the relevant parts that are needed for a particular design. The conflicting national standards will be withdrawn at the end of the coexistence period, after all the EN Eurocodes of a package are available. Following publication of the EN, there is a period of two years allowed for the national calibration period during which the national annex is issued, followed by a three year coexistence period. During the coexistence period Member States will be encouraged to adapt their national provisions to withdraw conflicting national rules before the end of the coexistence period. The Commission in consultation with Member States is expected to agree the end of the coexistence period for each package of Eurocodes. At the end of this coexistence period, the national standard will be withdrawn. In the UK, the corresponding national standard is BS 5400-51979, Steel, concrete and composite bridges Code of practice for design of composite bridges and based on this transition period this standard will be withdrawn on a date to be announced. The UK participation in its preparation was entrusted by Technical Committee B/525, Building and civil engineering structures, to Subcommittee B/525/4, Composite structures, which has the responsibility to A list of organizations represented on this subcommittee can be obtained on request to its secretary. aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep UK interests ined; monitor related international and European developments and promulgate them in the UK.

NDPs can be a specific value for a factor, a specific level or class, a particular or a particular application rule if several are proposed in the EN. To enable EN 1994-2 to be used in the UK, the NDPs will be published in a national annex, which will be made available by BSI in due course, after public consultation has taken place.
