Foreword
This document (EN 1991-1-1:2002) has been prepared by Technical Committee
CEN/TC 250 "Structural Eurocodes", the secretariat of which is held by BSI.
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 October 2002, 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conflicting national standards shall be withdrawn at the latest by March 2010.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 1991-2-1:1995.
The annexes A and B are informative.
According to the CEN/CENELEC Internal Regulations, the national standards
organizations of the following countries are bound to implement this European
Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany,
Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal,
Spain, Sweden, Switzerland and the 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 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 serve 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 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 between 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 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

Agreement 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).
construction products - CPD - and Council Directives 93/37/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:
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
EN 1998 Eurocode 8: Design of structures for earthquake resistance
EN 1999 Eurocode 9: Design of aluminium structures
Eurocode standards recognise 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 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 building and civil engineering works with the
essential requirements of Council Directive 89/106/EEC, particularly Essential
Requirement N°1 – Mechanical resistance and stability – and Essential Requirement
N°2 – Safety in case of fire ;
– as a basis for specifying contracts for cons
