6、t 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). NDPs can be a specific value for a factor, a specific level or class, a particular method or a

7、particular application rule if several are proposed in the EN. To enable BS EN 1993-1-1:2005+A1:2014 to be used in the UK the latest version of the NA to this Standard containing these NDPs should also be used. At the time of publication, it is NA+A1:2014 to BS EN 1993-1-1:2005+A1:2014.BSI, as a mem

8、ber of CEN, is obliged to publish EN 1993-1-1:2005+A1:2014 as a British Standard. However, attention is drawn to the fact that during the development of this amendment to this European Standard, the UK committee voted against its approval.The UK voted against its approval due to objections to the te

9、chnical content of Annex C relating to the achievement of structural reliability. These objections have largely been addressed in the UK decisions on C.2.2 (3) and C.2.2 (4) in the NA+A1:2014 to BS EN 1993-1-1:2005+A1:2014.The UK participation in its preparation was entrusted to Technical Committee

CEN/TC250 is responsible for all Structural Eurocodes. This European Standard shall be gi

28、ven the status of a National Standard, either bypublication of an identicaltext orbyendorsement, at the latest byNovember 2005, and conflicting National Standards shall be withdrawnat latest by March 2010. This Eurocode supersedes ENV1993-1-1. According to the CEN-CENELEC Internal Regulations, the N

29、ational Standard Organizations of the following countries are bound to implement these European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland,

30、 Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. Background of the Eurocode programme In 1975, the Commission of the European Communitydecided on an action programme in the field of construction, based on article 95 of the Treaty. The objective of the programme was the e

31、limination of technical obstacles to trade and the harmonization of technical specifications. Within this action programme, the Commission took the initiative to establish a set of harmonized technical rules for the design of construction works which, in a first stage, would serve as an alternative

32、to the national rules in force in the Member States and, ultimately, would replace them. For fifteen years, the Commission, with the help of a Steering Committee with Representatives of Member States, conducted the development of the Eurocodes programme, which led to the first generation of European

33、 codes in the 1980s. In 1989, the Commission and the Member States of the EU and EFTA decided, on the basis of an agreement1between the Commission and CEN, to transfer the preparation and the publication of the Eurocodes to the CEN through a series of Mandates, in order to provide themwith a future

34、status of European Standard (EN). This links de facto the Eurocodes with the provisions of all the Councils Directives and/or Commissions Decisions dealing with European standards (e.g. the Council Directive 89/106/EEC on construction products CPD and Council Directives 93/37/EEC, 92/50/EEC and 89/4

35、40/EEC on public works and services and equivalent EFTA Directives initiated in pursuit of setting up the internal market).
