Background to the Eurocode programme

(4) The Commission of the European Communities (CEC) initiated the work of establishing a set of harmonized technical rules for the design of building works and civil engineering works which would initially serve as an alternative to the different rules in force in the various Member States and would ultimately replace them. These technical rules became known as the 'Structural Eurocodes'. (5) In 1990, after consulting their respective Member States, the CEC transferred the work of further...

BSI British Standards Institution

BSI is the independent national body responsible for preparing British Standards. It presents the UK view on standards in Europe and at the international level. It is incorporated by Royal Charter. British Standards are updated by amendment or revision. Users of British Standards should make sure that they possess the latest amendments or editions. It is the constant aim of BSI to improve the quality of our products and services. We would be grateful if anyone finding an inaccuracy or ambiguity...

Objectives of the Eurocodes

(1 ) The Structural Eurocodes comprise a group of standards for the structural and geotechnical design of buildings and civil engineering works. (2) They cover execution and control only to the extent that is necessary to indicate the quality of the construction products, and the standard of the workmanship, needed to comply with the assumptions of the design rules. (3) Until the necessary set of harmonised technical specifications for products and for methods of testing their performance is...

Within this context this Prestandard has been established with two main objectives - to be sufficiently precise and comprehensive for contractual use, - to be sufficiently flexible to allow the relevant authorities and their designers fully to exert their technical responsibilities. (15) Because of the responsibilities of public authorities for bridges, it has been anticipated that, for the application of this Part, it will be supplemented by - general complementary rules and options to be...

Note For the selection of a traffic type, it may broadly be considered that - Long distance means hundreds of kilometres, - Medium distance means 50 to 100 km, - Local traffic means distances less than 50 km. In reality, mixture of traffic types may occur.
