Eurocode 1 - Actions on structures - Part 2: Traffic loads on bridges and other civil engineering works
(1) This document defines imposed loads (models and representative values) associated with road traffic, pedestrian actions and rail traffic which include, when relevant, dynamic effects and centrifugal, braking and acceleration actions and actions for accidental design situations.
(2) Imposed loads defined in this document are applicable for the design of new bridges, including piers, abutments, upstand walls, wing walls and flank walls, noise barriers, canopies etc., and their foundations. Where appropriate, the loads can also be considered as a basis for assessment or modification of existing structures in combination with complementary conditions if necessary.
(3) The load models and values given in this document are also applicable for the design of retaining walls adjacent to roads and railway lines and the design of earthworks subject to road or rail traffic actions. This document also provides applicability conditions for specific load models.
(4) This document is intended to be used with prEN 1990, the other parts of the EN 1991 series and the EN 1992 series to EN 1999 series for the design of structures.

(1) Dieses Dokument definiert Nutzlasten (Modelle und repräsentative Werte) in Verbindung mit Straßenverkehr, Einwirkungen durch Fußgänger und Schienenverkehr, gegebenenfalls einschließlich dynamischer Auswirkungen und Fliehkräften, Einwirkungen infolge Bremsen und Anfahren sowie Einwirkungen für außergewöhnliche Bemessungssituationen.
(2) Die in diesem Dokument definierten Nutzlasten sind anwendbar für die Bemessung neuer Brücken, einschließlich der Pfeiler, Widerlager, Kammerwände, Flügelwände, Lärmschutzwände, Dächer usw. und ihrer Gründungen. Gegebenenfalls können die Lasten auch als Grundlage für die Bewertung oder Änderung bestehender Tragwerke, falls erforderlich, in Kombination mit ergänzenden Bedingungen betrachtet werden.
(3) Die in diesem Dokument angegebenen Lastmodelle und Werte sind auch für die Bemessung von an Straßen- und Eisenbahnstrecken angrenzenden Stützwänden sowie die Bemessung von Erdarbeiten unter Einwirkungen infolge Straßen- oder Schienenverkehr anwendbar. Dieses Dokument enthält darüber hinaus Anwendbarkeitsbedingungen für spezifische Lastmodelle.
(4) Dieses Dokument ist für die Anwendung in Zusammenhang mit prEN 1990 vorgesehen, den anderen Teilen der Normenreihe EN 1991 und der Normenreihen EN 1992 bis EN 1999 für die Bemessung von Tragwerken.
Eurocode 1 - Actions sur les structures - Partie 2: Actions dues au trafic sur les ponts et autres ouvrages du génie civil
(1) Le présent document spécifie les charges d’exploitation (modèles et valeurs représentatives) associées au trafic routier, à la circulation des piétons et au trafic ferroviaire, y compris, le cas échéant, les effets dynamiques, les forces centrifuges, les forces de freinage et les forces d’accélération ainsi que les actions pour les situations de projet accidentelles.
(2) Les charges d’exploitation définies dans le présent document sont applicables au calcul des ponts neufs, piles, culées, murs garde grève, murs en aile et en retour, écrans antibruit, abris, etc., ainsi que de leurs fondations. Le cas échéant, les charges peuvent également être considérées comme une base pour l’évaluation ou la modification des structures existantes en combinaison avec des conditions complémentaires si nécessaire.
(3) Les modèles de charge et les valeurs donnés dans le présent document sont également applicables au calcul des murs de soutènement bordant les routes et les voies ferrées et au calcul des remblais soumis aux actions du trafic routier ou ferroviaire. Le présent document fournit également les conditions d’application pour des modèles de charge spécifiques.
(4) Le présent document est destiné à être utilisé avec le prEN 1990, les autres parties de la série EN 1991 ainsi que les séries EN 1992 à EN 1999 relatives au calcul des structures.
Evrokod 1 - Vplivi na konstrukcije - 2. del: Prometna obtežba mostov in drugih gradbenih inženirskih objektov
(1) Ta dokument opredeljuje obtežbe (modele in reprezentativne vrednosti), povezane s cestnim prometom, pešci in železniškim prometom, ki vključujejo, kjer je ustrezno, dinamične učinke in centrifugalne, zavorne in pospeševalne sile in ukrepe za načrtovanje v primeru nezgod.
(2) Obtežbe, opredeljene v tem dokumentu, se uporabljajo za projektiranje novih mostov, vključno s stebri, oporniki, pokončnimi zidovi, stranskimi zidovi in bočnimi zidovi, protihrupnimi pregradami, nadstreški itd. in njihovimi temelji. Kjer je to ustrezno, je obtežbe mogoče upoštevati kot osnovo za ocenjevanje ali spreminjanje obstoječih konstrukcij v kombinaciji z dopolnilnimi pogoji po potrebi.
(3) Modeli in vrednosti obtežb, podani v tem dokumentu, se uporabljajo tudi za načrtovanje opornih zidov ob cestah in železniških progah in tudi zemeljskih del, na katere delujejo sile cestnega ali železniškega prometa. Ta dokument določa veljavne pogoje za posebne modele obtežb.
(4) Ta dokument je namenjen uporabi s standardom EN 1990, drugimi deli skupine standardov EN 1991 in skupino standardov od EN 1992 do EN 1999 za projektiranje konstrukcij.
