In the Directive on the application and use of Eurocodes, issued by the EU Commission, reference is made to transitional periods for the introduction of the Eurocodes in the

7、 Member states. It will be the responsibility of CEN and the EU Commission to agree the details of the introduction on a case-by-case basis. In Germany, this standard is to be applied in conjunction with the National Annex. Attention is drawn to the possibility that some of the elements of this docu

Amendments This standard differs from DIN V ENV 1998-5:1997-06 as follows: a) the prestandard status has been changed to that of a full standard; b) the comments rece

9、ived from the national member bodies of CEN have been taken into account and the standard has been completely revised. Compared with DIN EN 1998-5:2006-03 and DIN 4149:2005-04, the following corrections have been made: a) the standard has been based on European design rules; b) superseding notes hav

29、 Kingdom.Background of the Eurocode programmeIn 1975, the Commission of the European Community decided on an action programmein the field of construction, based on article 95 of the Treaty. The objective of theprogramme was the elimination of technical obstacles to trade and the harmonisation oftech

30、nical specifications.Within this action programme, the Commission took the initiative to establish a set ofharmonised technical rules for the design of construction works which, in a first stage,would serve as an alternative to the national rules in force in the Member States and,ultimately, would r

31、eplace them.For fifteen years, the Commission, with the help of a Steering Committee withRepresentatives of Member States, conducted the development of the Eurocodesprogramme, which led to the first generation of European codes in the 1980s.In 1989, the Commission and the Member States of the EU and

32、 EFTA decided, on thebasis of an agreement1between the Commission and CEN, to transfer the preparationand the publication of the Eurocodes to CEN through a series of Mandates, in order toprovide them with a future status of European Standard (EN). This links de facto theEurocodes with the provisions

33、 of all the Councils Directives and/or CommissionsDecisions dealing with European standards (e.g. the Council Directive 89/106/EEC onconstruction products - CPD - and Council Directives 93/37/EEC, 92/50/EEC and89/440/EEC on public works and services and equivalent EFTA Directives initiated inpursuit

34、 of setting up the internal market).1Agreement between the Commission of the 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).DIN EN 1998-5:2010-12 EN 1998-5:2004 (E)4 The S

37、uresEurocode standards recognise the responsibility of regulatory authorities in eachMember State and have safeguarded their right to determine values related to regulatorysafety matters at national level where these continue to vary from State to State.Status and field of application of EurocodesTh

38、e Member States of the EU and EFTA recognise that Eurocodes serve as referencedocuments for the following purposes: as a means to prove compliance of building and civil engineering works with theessential requirements of Council Directive 89/106/EEC, particularly EssentialRequirement N1 Mechanical r

39、esistance and stability and Essential RequirementN2 Safety in case of fire ; as a basis for specifying contracts for construction works and related engineeringservices ; as a framework for drawing up harmonised technical specifications for constructionproducts (ENs and ETAs)The Eurocodes, as far as

40、they concern the construction works themselves, have a directrelationship with the Interpretative Documents2referred to in Article 12 of the CPD,although they are of a different nature from harmonised product standards3. Therefore,technical aspects arising from the Eurocodes work need to be adequate

41、ly considered byCEN Technical Committees and/or EOTA Working Groups working on productstandards with a view to achieving full compatibility of these technical specificationswith the Eurocodes.2According to Art. 3.3 of the CPD, the essential requirements (ERs) shall be given concrete form in interpre

42、tative documents for thecreation of the necessary links between the essential requirements and the mandates for harmonised ENs and ETAGs/ETAs.3According to Art. 12 of the CPD the interpretative documents shall :a) give concrete form to the essential requirements by harmonising the terminology and th

43、e technical bases and indicating classesor levels for each requirement where necessary ;b) indicate methods of correlating these classes or levels of requirement with the technical specifications, e.g. methods ofcalculation and of proof, technical rules for project design, etc. ;c) serve as a refere

44、nce for the establishment of harmonised standards and guidelines for European technical approvals.The Eurocodes, de facto, play a similar role in the field of the ER 1 and a part of ER 2.DIN EN 1998-5:2010-12 EN 1998-5:2004 (E)5 The Eurocode standards provide common structural design rules for every

45、day use forthe design of whole structures and component products of both a traditional and aninnovative nature. Unusual forms of construction or design conditions are notspecifically covered and additional expert consideration will be required by the designerin such cases.National Standards implemen

46、ting EurocodesThe National Standards implementing Eurocodes will comprise the full text of theEurocode (including any annexes), as published by CEN, which may be preceded by aNational title page and National foreword, and may be followed by a National annex.The National annex may only contain inform

47、ation on those parameters which are leftopen 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 inthe country concerned, i.e. : values and/or classes where alternatives are given in the E

48、urocode, values 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.It may also contain decisions on the application of informative annexes, refer

49、ences to non-contradictory complementary information to assist the user toapply the Eurocode.Links between Eurocodes and harmonised technical specifications (ENs and ETAs)for productsThere is a need for consistency between the harmonised technical specifications forconstruction products and the technical rules for works4. Furthermore, all theinformation accompanying the CE Marking of the construction products which refer toEurocodes shall clearly mention which Nationally Determined
