Foreword
This European Standard EN 1992, Eurocode 2: Design of concrete structures: General rules and rules for buildings, has been prepared on behalf of Technical Committee CEN/TC250
« Structural Eurocodes », the Secretariat of which is held by BSI. CEN/TC250 is responsible for all Structural Eurocodes.
The text of the draft standard was submitted to the formal vote and was approved by CEN as EN 1992-1 on YYYY-MM-DD .
No existing European Standard is superded.
Background of the eurocode programme
In 1975, the Commission of the European Community decided on an action programme in the field of construction, bad on article 95 of the Treaty. The objective of 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 t of
harmonid technical rules for the design of construction works which, in a first stage, would rve as an alternative to the national rules in force in the Member States and, ultimately,would replace them.抱不平
For fifteen years, the Commission, with the help of a Steering Committee with Reprentatives of Member States, conducted the development of the Eurocodes programme, which led to the first 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 agreement 1 between the Commission and CEN, to transfer the preparation and the
publication of the Eurocodes to CEN through a ries of Mandates, in order to provide them with a fu
ture status of European Standard (EN). This links de facto the Eurocodes with the provisions of all the Council’s Directives and/or Commission’s 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 works and rvices and equivalent EFTA Directives initiated in pursuit of tting up the internal market).
The Structural Eurocode programme compris the following standards generally consisting of a number of Parts:
EN 1990
Eurocode :Basis of Structural Design EN 1991
Eurocode 1:Actions on structures 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:Geotechnical design 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).

Eurocode standards recogni the responsibility of regulatory authorities in each Member State and have safeguarded their right to determine values related to regulatory safety matters at national level where the continue to vary from State to State.忘了微笑
Status and field of application of eurocodes黄芪的功效作用
The Member States of the EU and EFTA recogni that Eurocodes rve as reference documents for the following purpos :
– as a means to prove compliance of building and civil engineering works with the esntial requirements of Council Directive 89/106/EEC, particularly Esntial Requirement N°1 –Mechanical resistance and stability – and Esntial Requirement N°2 – Safety in ca of fire;– as a basis for specifying contracts for construction works and related engineering rvices;– as a framework for drawing up harmonid technical specifications for construction products (ENs and ETAs)
The Eurocodes, as far as they concern the construction works themlves, have a direct relationship with the Interpretative Documents 2 referred to in Article 12 of the CPD, although they are of a different nature from harmonid product standards 3. Therefore, technical aspects arising from the Eurocodes work need to be adequately considered by CEN Technical Committees and/or EOTA Wor
king Groups working on product standards with a view to achieving full compatibility of the technical specifications with the Eurocodes.
The Eurocode standards provide common structural design rules for everyday u for the design of whole structures 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 cas.

National standards implementing eurocodes
The National Standards implementing Eurocodes will compri 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 tho parameters which are left open in the Eurocode for national choice, known as Nationally Determined Parameters, to be ud for 2 According to Art. 3.3 of the CPD, the esntial requirements (ERs) shall be given concrete form in interpretative documents for the creation of the necessary links between the esntial requirements and the mandates for harmonid ENs and ETAGs/ETAs.
3 According to Art. 12 of the CPD the interpretative documents shall :
溜肉段做法a) give concrete form to the esntial requirements by harmonising the terminology and the technical bas and indicating class or levels for each requirement where necessary ;
b) indicate methods of correlating the class or levels of requirement with the technical specifications, e.g. methods of calculation and of proof,technical rules for project design, etc. ;
c) rve as a reference for the establishment of harmonid 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.

the design of buildings and civil engineering works to be constructed in the country :
– values and/or class where alternatives are given in the Eurocode,
– values to be ud where a symbol only is given in the Eurocode,
– country specific data (geographical, climatic, etc.), e.g. snow map,
– the procedure to be ud where alternative procedures are given in the Eurocode.It may contain
– decisions on the application of informative annexes,
– references to non-contradictory complementary information to assist the ur to apply the Eurocode.
Links between eurocodes and harmonid technical specifications (ENs and ETAs) for products
There is a need for consistency between the harmonid technical specifications for construction products and the technical rules for works 4. 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.Additional information specific to EN 1992-1
EN 1992-1 describes the principles and requirements for safety, rviceability and durability of concrete structures, together with specific provisions for buildings. It is bad on the limit state concept ud in conjunction with a partial factor method.
For the design of new structures, EN 1992-1 is intended to be ud, for direct application,together with other parts of EN 1992, Eurocodes EN 1990,1991, 1997 and 1998.
送生日蛋糕EN 1992-1 also rves as a reference document for other CEN TCs concerning structural matters.
E N 1992-1 is intended for u by:– committees drafting other standards for structural design and related product, testing and execution standards;
– clients (e.g. for the formulation of their specific requirements on reliability levels and durability);– designers and constructors ;
– relevant authorities.
Numerical values for partial factors and other reliability parameters are recommended as basic values that provide an acceptable level of reliability. They have been lected assuming that an appropriate level of workmanship and of quality management applies. When EN 1992-1 is ud as a
ba document by other CEN/TCs the same values need to be taken.
National annex for EN 1992-1
This standard gives values with notes indicating where national choices may have to be made.Therefore the National Standard implementing EN 1992-1 should have a National annex
containing all Nationally Determined Parameters to be ud for the design of buildings and civil 4 e Art.3.3 and Art.12 of the CPD, as well as claus 4.2, 4.3.1, 4.3.2 and 5.2 of ID 1.
