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...

The spectral density < 1> (Q) is given by For a rough and quick estimation of the roughness quality, the following guidance is given - actual roadway layers, such as, for example, asphalt or concrete layers, can be assumed to have a good or even a very good roughness quality - old roadway layers which are not maintained may be classified as having a medium roughness - roadway layers consisting of cobblestones or similar material may be classified as medium (average) or bad (poor, very...

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. Table 4.8 Definition of wheels and axles 4.6.6 Fatigue Load Model 5 based on recorded road traffic 1 Fatigue Load Model 5 consists of the direct application of recorded traffic data, supplemented, if relevant, by appropriate statistical and...

Matters specific to this Prestandard

18 The scope of Eurocode 1 is defined in clause 1.1.1 and the scope of this Part of Eurocode 1 is defined in clause 1.1.2. Additional Parts of Eurocode 1 which are planned are indicated in clause 1.1.3. 19 This Prestandard is divided into six sections - three general sections 1 to 3 of common clauses - three sections 4 to 6 dealing with road traffic loads, pedestrian and cycle loads, and railway traffic loads, respectively, and also with other loads specifically for road bridges, footbridges...
