This European Standard shall be given the status of a National Standard, either by publication of an identical text or by endors
37、ement, at the latest by November 2005, and conflicting National Standards shall be withdrawn at latest by March 2010. This Eurocode supersedes ENV1993-1-1. According to the CEN-CENELEC Internal Regulations, the National Standard Organizations of the following countries are bound to implement these E

Background
39、 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 technical obstacles to trade and the harmonization of technical specifica
40、tions. 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 rules in force in the Member States and, ultimately, would replace them
41、. 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 d
42、ecided, on the basis of an agreement1 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 o
43、f 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 works and services and equivalent EFTA Directives initiated in pursu
44、it 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 structures EN 1992 Eurocode 2: Design of concrete structures EN 1993 Eur

Status and field of application of eurocodes The Member States of the EU and EFTA recognize that Eurocodes serve as reference documents for the following purposes : as a means to prove compliance of building and civil engineering work
