24、y BSI. CEN/TC 250 is responsible for all Structural Eurocodes. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2005, and conflicting national standards shall be withdrawn at the latest by
25、 March 2010. This document supersedes ENV 1993-1-1:1992. Background to 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 the programme was the elimination of techni
26、cal 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 to the national rule
27、s 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 codes in the 1980s.
28、 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 CEN through a series of Mandates, in order to provide them with a future status of European Stan
29、dard (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 89/440/EEC on public wo
30、rks 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: EN 1990 Eurocode 0: Basis of Structural Design EN 1991 Eurocode 1: Actions on struct
31、ures EN 1992 Eurocode 2: Design of concrete structures EN 1993 Eurocode 3: Design of steel structures EN 1994 Eurocode 4: Design of composite steel and concrete structures EN 1995 Eurocode 5: Design of timber structures EN 1996 Eurocode 6: Design of masonry structures EN 1997 Eurocode 7: Geotechnica
32、l design EN 1998 Eurocode 8: Design of structures for earthquake resistance EN 1999 Eurocode 9: Design of aluminium structures 1Agreement between the Commission of the European Communities and the European Committee for Standardisation (CEN) concerning the work on EUROCODES for the design of buildin
33、g and civil engineering works (BC/CEN/03/89). According to the CEN-CENELEC Internal Regulations, the National Standard Organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Franc
34、e, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. DIN EN 1993-1-9:2010-12 EN 1993-1-9:2005 + AC:2009 (E) 4 Eurocode standards recognize the res
35、ponsibility of regulatory authorities in each Member State and have safeguarded their right to determine values related 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 r
36、ecognize that Eurocodes serve as reference documents for the following purposes : as a means to prove compliance of building and civil engineering works with the essential requirements of Council Directive 89/106/EEC, particularly Essential Requirement N1 Mechanical resistance and stability and Esse
37、ntial Requirement N2 Safety in case of fire; as a basis for specifying contracts for construction works and related engineering services; as a framework for drawing up harmonized technical specifications for construction products (ENs and ETAs) The Eurocodes, as far as they concern the construction
38、works themselves, have a direct relationship with the Interpretative Documents2referred to in Article 12 of the CPD, although they are of a different nature from harmonized product standards3. Therefore, technical aspects arising from the Eurocodes work need to be adequately considered by CEN Techni
39、cal 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 structures and component pro
40、ducts 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 Standards implementing Euro
41、codes 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. The National annex may only contain information on those parameters which are left open in th
42、e 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 to be used where a symbol only i
43、s 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 contain decisions on the application of informative annexes, references to non-contradictory complementary information
44、 to assist the user to apply the Eurocode. 2According to Art. 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 the essential requirements and the mandates for harmonized ENs and ETAGs/ETAs. 3 Acc
45、ording to Art. 12 of the CPD the interpretative documents shall : a) give concrete form to the essential requirements by harmonizing the terminology and the technical bases and indicating classes or levels for each requirement where necessary ; b) indicate methods of correlating these classes or lev
46、els of requirement with the technical specifications, e.g. methods of calculation and of proof, technical rules for project design, etc. ; c) serve as a reference for the establishment of harmonized standards and guidelines for European technical approvals. The Eurocodes, de facto, play a similar ro
47、le in the field of the ER 1 and a part of ER 2. DIN EN 1993-1-9:2010-12 EN 1993-1-9:2005 + AC:2009 (E) 5 Links between Eurocodes and harmonized technical specifications (ENs and ETAs) for products There is a need for consistency between the harmonized technical specifications for construction produc
48、ts and the technical rules for works4. Furthermore, all the information accompanying the CE Marking of the construction products which refer to Eurocodes should clearly mention which Nationally Determined Parameters have been taken into account. National annex for EN 1993-1-9 This standard gives alt
49、ernative procedures, values and recommendations with notes indicating where national choices may have to be made. The National Standard implementing EN 1993-1-9 should have a National Annex containing all Nationally Determined Parameters for the design of steel structures to be constructed in the relevant country. National choice is allowed in EN 1993-1-9 through: 1.1(2) 2(2) 2(4) 3(2) 3(7) 5(2) 6.1(1) 6.2(2) 7.1(3) 7.1(5) 8(4) 4see Art.3.3 and Art.12 of the CPD, as well as clauses 4.2, 4.3.1, 4.3.2 and
