Eurocode programme

(7) Work is in hand on the following Structural Eurocodes, each generally consisting of a number of Parts :

EN 1991 Eurocode 1 Basis of design and 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 alloy structures

(8) A separate sub-committee has been formed by CEN/TC250 for each of Eurocodes listed above.

(9) This Part of ENV 1991, which has benefited from preliminary studies made by CEC and UIC (Union Internationale des Chemins de Fer), and has been finalised in accordance with a mandate issued by CEC, is being published as a European Prestandard with an initial life of three years.

(10) This Prestandard is intended for experimental application.

(11) After approximately two years CEN members will be invited to submit formal comments on this Prestandard to be taken into account in determining future action.

(12) Meanwhile feedback and comments on this Prestandard should be sent to the Secretariat of Sub-committee CEN/TC250/SC1 at the following address :

or to your National Standards organisation. National Application Documents

(13) In view of the responsibilities of authorities in member countries for safety, health and other matters covered by the essential requirements of the Construction Products Directive (CPD), certain safety elements in this ENV have been assigned indicative values which are identified by I I or [ ] ("boxed values"). The authorities in each member country are expected to review the "boxed values" and may substitute alternative definitive values for these safety elements for use in national application.

(14) Bridges are essentially public works, for which :

- the European Directive 89/440/CEC on contracts for public works is particularly relevant, and

- public authorities have responsibilities as owners.

In addition, public authorities also have responsibilities for the issue of regulations on authorised traffic (especially on vehicle loads) and for delivery and control dispensations when relevant, eg. for special vehicles. In this respect, it is assumed that the authorities having these responsibilities will cooperate closely with those responsible for the design and reassessment of bridges (see the clauses and Notes dealing with the basis and conditions of numerical validity of this Prestandard).
