4、text by tags. Tags indicating changes to CEN text carry the number of the CEN corrigendum. For example, text altered by April 2009 corrigendum is indicated by .The structural Eurocodes are divided into packages by grouping Eurocodes for each of the main materials: concrete, steel, composite concrete

5、 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 The conflicting national standards will be withdrawn at the end of the co-existence period, after all the EN Eurocodes of a package are a

6、vailable.Following publication of the EN, there is a period allowed for national calibration during which the National Annex is issued, followed by a co-existence period of a maximum three years. During the co-existence period Member States are encouraged to adapt their national provisions. At the e

7、nd of this co-existence period, the conflicting parts of national standard(s) will be withdrawn.In the UK there are no conflicting national standards.The UK participation in its preparation was entrusted by Technical Committee B/525, Building and civil engineering structures, to Subcommittee B/525/3

8、1, Structural use of steel.A list of organizations represented 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 as Recommended Val

9、ues, 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 have been pub

10、lished in a National Annex, which has been issued separately by BSI.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 legal obligations.EUROPEAN ST

NOTE: Due to the requi

29、rement of adjustability and replaceability such tension components are generally prefabricated products delivered to site and installed into the structure. Tension components that are not adjustable or replaceable, e.g. air spun cables of suspension bridges, or for externally post-tensioned bridges,

30、 are outside the scope of this part. However, rules of this standard may be applicable. (2) This standard also gives rules for determining the technical requirements for prefabricated tension components for assessing their safety, serviceability and durability.
