It supersedes DD ENV 1993-1-3:2001 which is withdrawn. It
3、partially supersedes BS 5950-5:1998, BS 5950-6:1995 and BS 5950-9:1994.The start and finish of text introduced or altered by corrigendum is indicated in the text by tags. Text altered by CEN corrigendum November 2009 is indicated in the text by .The UK participation in its preparation was entrusted
4、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 this subcommittee can be obtained on request to its secretary.The structural Eurocodes are divided into packages by grouping Eurocodes for
5、 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 The conflicting national standards will be withdrawn at the end of the co
6、existence 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 coexistence period Member Stat
7、es 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 Conflicting national standards will be withdrawn by March 2010 at the latest.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 normative text, and a note will q
8、ualify 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 1993-1-3 to be used in the UK, the NDPs will be published in a National Ann
9、ex, 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 Standard cannot confer immunity from le

24、 This European Standard EN 1993-1-3, Eurocode 3: Design of steel structures: Part 1-3 General rules Supplementary rules for cold formed members and sheeting, has been prepared by Technical Committee CEN/TC250 Structural Eurocodes , the Secretariat of which is held by BSI. CEN/TC250 is responsible fo
25、r all Structural Eurocodes. This European Standard shall be given the status of a National Standard, either by publication of an identical text or by endorsement, at the latest by April 2007, and conflicting National Standards shall be withdrawn at latest by March 2010. This Eurocode supersedes ENV
26、1993-1-3. According to the CEN-CENELEC Internal Regulations, the National Standard Organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, L
27、atvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. National annex for EN 1993-1-3 This standard gives alternative procedures, values and recommendations for classes with notes indicating where nation
28、al choices may have to be made. Therefore the National Standard implementing EN 1993-1-3 should have a National Annex containing all Nationally Determined Parameters to be used for the design of steel structures to be constructed in the relevant country. National choice is allowed in EN 1993-1-3 thr

30、ope (1) EN 1993-1-3 gives design requirements for cold-formed members and sheeting. It applies to cold-formed steel products made from coated or uncoated hot or cold rolled sheet or strip, that have been cold-formed by such processes as cold-rolled forming or press-braking. It may also be used for t
31、he design of profiled steel sheeting for composite steel and concrete slabs at the construction stage, see EN 1994. The execution of steel structures made of cold-formed members and sheeting is covered in EN 1090. NOTE: The rules in this part complement the rules in other parts of EN 1993-1. (2) Met
32、hods are also given for stressed-skin design using steel sheeting as a structural diaphragm. (3) This part does not apply to cold-formed circular and rectangular structural hollow sections supplied to EN 10219, for which reference should be made to EN 1993-1-1 and EN 1993-1-8. (4) EN 1993-1-3 gives
33、methods for design by calculation and for design assisted by testing. The methods for design by calculation apply only within stated ranges of material properties and geometrical proportions for which sufficient experience and test evidence is available. These limitations do not apply to design assi
34、sted by testing. (5) EN 1993-1-3 does not cover load arrangement for testing for loads during execution and maintenance. (6) The calculation rules given in this standard are only valid if the tolerances of the cold formed members comply with EN 1090-2 1.2 Normative references The following normative
35、 documents contain provisions which, through reference in this text, constitute provisions of this European Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this European Standard are encouraged
36、 to investigate the possibility of applying the most recent editions of the normative documents indicated below.
