BRITISH STANDARD BS EN 1994-1-12004 Eurocode 4 Design of composite steel and concrete structures Part 1-1 General rules and rules for buildings The European Standard EN 1994-1-12004 has the status of a British Standard ICS 91.010.30; 91.080.10; 91.080.40 Licensed Copy x x, University of Glamorgan, Mon Apr 23 190647 GMT0000 2007, Uncontrolled Copy, c BSI BS EN 1994-1-12004 This British Standard was published under the authority of the Standards Policy and Strategy Committee on 18 February 2005 BSI 18 February 2005 ISBN 0 580 45569 6 National foreword This British Standard is the official English language version of EN 1994-1-12004. It supersedes DD ENV 1994-1-11994 which is withdrawn.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 The conflicting national standards will be withdrawn at the end of the coexistence period, after all the EN Eurocodes of a package are available.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 2 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 coexistent 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 At the end of this coexistence period, the national standards will be withdrawn. In the UK, the corresponding national standards are; and based on this transition period, these standards will be withdrawn on a date to be announced.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.
