In 1975, the Commission of the European Community decided on an action programme in the field of construction with the objective to eliminate technical obstacles to trade and the harmonisation of technical specifications within the member states.
For fifteen years the Commission conducted the development of the Eurocodes programme, which led to the first generation of European codes in the 1990s.
The Commission decided then to transfer the preparation and the publication of the Eurocodes to the European Committee for Standardization (CEN), in order to provide them with a future status of European Standard (EN).
The eurocodes are the ten European standards (EN harmonised technical rules) specifying how structural design should be conducted within the European Union (EU). Ten eurocodes have been developed and published, each having a number of parts:
The national standard bodies are responsible for implementing and issuing a National Annex to the Eurocodes which will need referencing for a particular country.
The purpose of the eurocodes is to provide:
*A public standards organization whose mission is to foster the economy of the European Union by maintaining and developing coherent sets of standards and specifications.
The purpose of the Eurocodes is to identify common regulations for the following fields:
The National Annex (NA) is an essential document containing the entire the text of the Eurocode as published by the CEN. It specifies the parameters of civil engineering structures for each nation, such as
Although the NA may specify the value of partial factors to be applied to actions and resistances, in many cases it simply accepts the value recommended in the Eurocode text. In Italy, Eurocodes are enforced as of ministerial decree of 31 July 2012. The guidance given in a National Annex applies to structures that are to be constructed within that country. National Annexes are likely to differ between countries within Europe. The National Annexes for the country where the structure is to be constructed should always be consulted in the design of a structure, such as NTC 2008/2018 for Italy.
