3、y of the Standards Policy and Strategy Committee on 30 November 2006 BSI 2006ISBN 0 580 49666 XNational forewordThis British Standard was published by BSI. It is the UK implementation of EN 1993-1-4:2006. The UK participation in its preparation was entrusted by Technical Committee B/525, Building an

4、d 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 packages by grouping Eurocodes for each of the main materials: concrete, steel, comp

5、osite 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 The conflicting national standards will be withdrawn at the end of the coexistence period, after all the EN Eurocodes of a

6、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 States are encouraged to adapt their national provisio

7、ns. Conflicting national standards will be withdrawn by March 2010 at the latest.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 qualify it as a Nationally Determined Parameter (ND

8、P). 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 1993-1-4 to be used in the UK, the NDPs will be published in a National Annex, which will be made available by BSI in due cou

43、n using austenitic, austenitic-ferritic and ferritic stainless steels. (2) The nominal values of the material properties given in 2.1.2 should be used as characteristic values in structural design calculations. (3) For further information about material properties reference should be made to EN 1008

44、8. (4) The design provisions specified in this Part 1.4 are applicable for material of nominal yield strength fy up to and including 480 N/mm2. NOTE: Rules for the use of work hardened material with fy 480 N/mm2 are given in Informative Annex B. (5) The higher strength of other materials (see 2.1.2

45、and Annex B) may be taken into account in the design provided that doing so is justified by appropriate tests in accordance with Section 7. 2.1.2 Material properties for stainless steel (1) In design calculations the values should be taken as follows, independent of the direction of rolling: - yield

46、 strength fy: the nominal stress (0,2% proof stress) specified in Table 2.1; - ultimate tensile strength fu: the nominal ultimate tensile strength specified in Table 2.1. (2) The ductility requirements in EN 1993-1-1, clause 3.2.2 also apply to stainless steels. Steels conforming with one of the ste

47、el grades listed in Table 2.1 should be accepted as satisfying these requirements. (3) For structural hollow sections, the strength values given in Table 2.1 for the relevant product form of the base material (cold-rolled strip, hot rolled strip or hot rolled plate) should be used. (4) Higher streng

48、th values derived from cold working the base material may be used in design provided they are verified by tests on coupons taken from the structural hollow section in accordance with Section 7. (5) For cold worked material, the material tests given in the material certificate required according to E

49、N 1090, should be in such a direction that the strength values used in design are independent of the direction of rolling or stretching.
