1、BRITISH STANDARD BS EN 1994-1-1:2004 Eurocode 4: Design of composite steel and concrete structures Part 1-1: General rules and rules for buildings ICS 91.010.30; 91.080.10; 91.080.40 Incorporating corrigendu m April 2009National foreword This British Standard is the UK implementation of EN 1994-1-1:

2、2004, incorporating corrigendum April 2009. It supersedes DD ENV 1994-1-1:1994 which is withdrawn. The start and finish of text introduced or altered by corrigendum is indicated in the text by tags. Text altered by CEN corrigendum April 2009 is indicated in the text by . The structural Eurocodes are

3、 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

4、standards will be withdrawn at the end of the co-existence period, after all the EN Eurocodes of a package are available. Following publication of the EN, there is a period allowed for the national calibration during which the National Annex is issued, followed by a co-existence period of a maximum

5、three years. During the co-existence period Member States are encouraged to adapt their national provisions. At the end of this co-existence period, the conflicting parts of national standard(s) will be withdrawn. In the UK, the primary corresponding national standards are: BS 5950-3.1:1990 Structur

6、al use of steelwork in building. Design in composite construction. Code of practice for design of simple and continuous composite beams. BS 5950-4:1994 Structural use of steelwork in building. Code of practice for design of composite slabs with profiled steel sheeting. and based on this transition p

7、eriod, these standards will be withdrawn on a date to be announced, but at the latest by March 2010. 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. A list of organizations r

8、epresented on this subcommittee can be obtained on request to its secretary. Where a normative part of this EN allows for a choice to be made at the national level, the range and possible choice will be given in the normative text, and a note will qualify it as a Nationally Determined Parameter (NDP

9、). 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 1994-1-1 to be used in the UK, the NDPs will be published in a National Annex, which will be made available by BSI in due cour

10、se, 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.
