(Main)Eurocode 5 - Design of timber structures - Part 2: Bridges
Eurocode 5 - Design of timber structures - Part 2: Bridges
1.1 Scope of EN 1995-2
(1) This document 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.
(2) Prestressed timber-concrete composite (TCC) members are not covered by this document. The design of stress-laminated timber decks used as part of a TCC system is covered.
(3) Systems which rely on friction between wood and concrete are not covered by this document.
1.2 Assumptions
(1) The assumptions of EN 1990 apply to this document.
(2) It is assumed that the requirements for execution given in EN 1995 3 are complied with.
Eurocode 5 - Bemessung und Konstruktion von Holzbauten - Teil 2: Brücken
1.1 Anwendungsbereich von EN 1995 2
(1) Dieses Dokument enthält allgemeine Bemessungsregeln für die Tragwerksteile von Brücken, d. h. tragende Bauteile, die wichtig für die Zuverlässigkeit der gesamten oder Hauptteile der Brücke sind. Diese bestehen aus Holz oder anderen Holzwerkstoffen, gegebenenfalls im Verbund mit Beton, Stahl oder anderen Baustoffen.
(2) Vorgespannte Holz-Beton-Verbund (HBV)-Bauteile werden in diesem Dokument nicht behandelt. Die Bemessung von als Teil eines HBV-Systems verwendeten Deckplatten aus zusammengespannten Holzlamellen ist abgedeckt.
(3) Systeme, die sich auf die Reibung zwischen Holz und Beton stützen, werden in diesem Dokument nicht behandelt.
1.2 Voraussetzungen
(1) Für dieses Dokument gelten die Voraussetzungen nach EN 1990.
(2) Die Übereinstimmung mit den Anforderungen für die Ausführung nach EN 1995 3 wird vorausgesetzt.
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.
(2) Les éléments mixtes bois-béton (TCC) précontraints ne sont pas couverts par le présent document. Le calcul des tabliers en bois lamellé précontraint utilisés dans le cadre d'un système mixte bois-béton est couvert.
(3) Les systèmes qui reposent sur le frottement entre le bois et le béton ne sont pas couverts par le présent document.
1.2 Hypothèses
(1) Les hypothèses de l'EN 1990 s'appliquent au présent document.
(2) Il est supposé que les exigences d'exécution données dans l'EN 1995 3 sont respectées.

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.
