Text altered by CEN corrigendum October 2009 is indicated in the text by .The structural Eurocodes are divided into packages by grouping Eurocodes for each of the main materials, concrete, steel, composite concrete a
4、nd 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 The conflicting national standards will be withdrawn at the end of the co-existence period, after all the EN Eurocodes of a package are ava
5、ilable.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 will be encouraged to adapt their national provisions. At the
6、 end of this co-existence period, the conflicting parts of national standard(s) will be withdrawn.In the UK, the corresponding national standards are: BS 5628-1:1992, Code of practice for use of masonry. Structural use of unreinforced masonry BS 5628-2:2000, Code of practice for use of masonry. Stru

This European Standard shall be given the status of a national standard, either by pub
27、lication of an identical text or by endorsement, at the latest by July 2006, and conflicting national standards shall be withdrawn at the latest by March 2010. CEN/TC 250 is responsible for all Structural Eurocodes. This document supersedes ENV 1996-3:1999 According to the CEN/CENELEC Internal Regul
28、ations, the national standards 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, Latvia, Lithuania, Luxembourg, Malta, Netherlands, No
29、rway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. Background of the Eurocode programme In 1975, the Commission of the European Community decided on an action programme in the field of construction, based on article 95 of the Treaty. The objective of
30、the programme was the elimination of technical obstacles to trade and the harmonisation of technical specifications. Within this action programme, the Commission took the initiative to establish a set of harmonised technical rules for the design of construction works which, in a first stage, would s
31、erve as an alternative 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
32、 generation of European 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 pro
33、vide them with a future 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/
34、37/EEC, 92/50/EEC and 89/440/EEC on public works and services and equivalent EFTA Directives initiated in pursuit of setting up the internal market). The Structural Eurocode programme comprises the following standards generally consisting of a number of Parts: 1Agreement between the Commission of th
35、e European Communities and the European Committee for Standardisation (CEN) concerning the work on Eurocodes for the design of building and civil engineering works (BC/CEN/03/89).

Eurocode standards recognise the responsibility of regulatory authorities in each Member State and have safeguarded their right to determine values rela
38、ted to regulatory safety matters at national level where these continue to vary from State to State. Status and field of application of Eurocodes The Member States of the EU and EFTA recognise that Eurocodes serve as reference documents for the following purposes: as a means to prove compliance of b
39、uilding and civil engineering works with the essential requirements of Council Directive 89/106/EEC, particularly Essential Requirement N1 Mechanical resistance and stability and Essential Requirement N2 Safety in case of fire; as a basis for specifying contracts for construction works and related e
40、ngineering services; as a framework for drawing up harmonised technical specifications for construction products (ENs and ETAs). The Eurocodes, as far as they concern the construction works themselves, have a direct relationship with the Interpretative Documents2referred to in Article 12 of the CPD,
41、 although they are of a different nature from harmonised product standards3. Therefore, technical aspects arising from the 2According to Article 3.3 of the CPD, the essential requirements (ERs) shall be given concrete form in interpretative documents for the creation of the necessary links between t
42、he essential requirements and the mandates for harmonised ENs and ETAGs/ETAs. 3According to Article 12 of the CPD the interpretative documents shall: a) give concrete form to the essential requirements by harmonising the terminology and the technical bases and indicating classes or levels for each r
43、equirement where necessary; b) indicate methods of correlating these classes or levels of requirement with the technical specifications, e.g. methods of calculation and of proof, technical rules for project design, etc.; BS EN 1996-3:2006EN 1996-3:2006 (E) 6 Eurocodes work need to be adequately cons
44、idered by CEN Technical Committees and/or EOTA Working Groups working on product standards with a view to achieving full compatibility of these technical specifications with the Eurocodes. The Eurocode standards provide common structural design rules for everyday use for the design of whole structur
45、es and component products of both a traditional and an innovative nature. Unusual forms of construction or design conditions are not specifically covered and additional expert consideration will be required by the designer in such cases. National Standards implementing Eurocodes The National Standar
46、ds implementing Eurocodes will comprise the full text of the Eurocode (including any annexes), as published by CEN, which may be preceded by a National title page and National foreword, and may be followed by a National Annex (informative). The National Annex may only contain information on those pa
47、rameters which are left open in the Eurocode for national choice, known as Nationally Determined Parameters, to be used for the design of buildings and civil engineering works to be constructed in the country concerned, i.e.: values and/or classes where alternatives are given in the Eurocode, values
48、 to be used where a symbol only is given in the Eurocode, country specific data (geographical, climatic, etc), e.g. snow map, the procedure to be used where alternative procedures are given in the Eurocode and it may also contain decisions on the application of informative annexes, references to non
49、-contradictory complementary information to assist the user to apply the Eurocode. Links between Eurocodes and harmonised technical specifications (ENs and ETAs) for products. There is a need for consistency between the harmonised technical specifications for construction products and the technical rules for works4. Furthermore, all the information accompanying the CE Marking of the construction products which refer to Eurocodes shall clearly mention which Nationally Determined Parameters have been taken into account.
