1、BRITISH STANDARD BS EN 1993-2:2006 Eurocode 3 Design of steel structures Part 2: Steel bridges The European Standard EN 1993-2:2006 has the status of a British Standard ICS 91.010.30; 91.080.10; 93.040 ? BS EN 1993-2:2006 This British Standard was published under the authority of the Standards Polic
2、y and Strategy Committee on 30 November 2006 BSI 2006 ISBN 0 580 49664 3 National foreword This British Standard was published by BSI. It is the UK implementation of EN 1993-2:2006. It partially supersedes BS 5400-3:2000. This standard will be withdrawn by March 2010 at the latest. The UK participat
3、ion in its preparation was entrusted by Technical Committee B/525, Building and civil engineering structures, to Subcommittee B/525/31, Structural use of steel. A list of organizations represented on B/525/31 can be obtained on request to its secretary. The structural Eurocodes are divided into pack
4、ages 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
5、withdrawn at the end of the coexistence period, after all the EN Eurocodes of a package are available.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 allowed for national calibration during which the National Annex is issued, followed by a coexistence period of a maximum three years. During the
6、coexistence period Member States are encouraged to adapt their national provisions. Conflicting national standards will be withdrawn by March 2010 at the latest. Where a normative part of this EN allows for a choice to be made at national level, the range and possible choice will be given in the nor
7、mative text, and a note will qualify it as a Nationally Determined Parameter (NDP). NDPs can be a specific value for a factor, a specific level or class, a particular method or a particular application rule if several are proposed in the EN. To enable EN 1993-1-11 to be used in the UK, the NDPs will
8、 be published in a National Annex, which will be made available by BSI in due course after public consultation has taken place. This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application. Compliance with a British Standa
