prEN 1995-2

Eurocode 5 - Design of timber structures - Part 2: Bridges

(1) EN 1995-2 gives general design rules for the structural parts of bridges, i.e. structural members of importance for the reliability of the whole bridge or major parts of it, made of timber or other wood-based materials, either singly or compositely with concrete, steel or other materials.

Eurocode 5 - Calcul des structures en bois - Partie 2 : Ponts

1.1   Domaine d'application de l'EN 1995 2
(1) Le présent document donne les règles générales de calcul des composants structuraux des ponts, par exemple les éléments porteurs conditionnant la fiabilité du pont ou de ses parties principales, qu'ils soient en bois ou autres matériaux à base de bois, utilisés isolément ou en association avec du béton, du métal ou tous autres matériaux.
1.2   Hypothèses
(1) Les hypothèses générales données dans l'EN 1990 s'appliquent.
(2) L'EN 1995 2 est destiné à être utilisé conjointement avec l'EN 1990, l'EN 1991 (toutes les parties), l'EN 1995 (toutes les parties), la norme CEN/TS 19103, l'EN 1997 (toutes les parties) et l'EN 1998 2.
(3) Les règles concernant les éléments mixtes bois-béton précontraints ne sont pas couvertes par le présent document. Les règles de calcul des tabliers en bois lamellé précontraint utilisés dans le cadre d'un système mixte bois-béton sont indiquées.
(4) Les systèmes qui reposent sur le frottement entre le bois et le béton ne sont pas couverts par le présent document, à l'exception des tabliers en bois lamellé précontraint.

This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee
CEN/TC 250.
If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations
which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.

This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,
Poland, Portugal, Republic of North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Türkiye and
United Kingdom.
Recipients of this draft are invited to submit, with their comments, notification of any relevant patent rights of which they are
aware and to provide supporting documentation.

Warning : This document is not a European Standard. It is distributed for review and comments. It is subject to change without
notice and shall not be referred to as a European Standard.
