Edition date: 2025-02-26
In Force
Available languages: English, French
Summary: 1.1 Scope of EN 1991-1-3 (1) EN 1991-1-3 gives principles and rules to determine the values of loads due to snow to be used for the structural design of buildings and civil engineering works. (2) This document does not apply to sites at altitudes above 1 500 m, unless otherwise specified. NOTE For rules for the treatment of snow loads for altitudes above 1 500 m, see 6.1. (3) This document does not give guidance on specialist aspects of snow loading, for example: - impact snow loads resulting from snow sliding off or falling from a higher roof; - changes in shape or size of the construction works due to the presence of snow or the accretion of ice which could affect the wind action; - loads in areas where snow is present all year round; - lateral loading due to snow creep (e.g. lateral loads exerted by drifts); - loads due to artificial snow. 1.2 Assumptions The assumptions given in EN 1990:2023, 1.2 apply.

1.1 Domaine d'application de l'EN 1991-1-3 (1) L'EN 1991-1-3 donne les principes et les règles pour déterminer les valeurs des charges dues à la neige à considérer pour le calcul structural des bâtiments et ouvrages de génie civil. (2) Le présent document ne s’applique pas aux sites d’une altitude supérieure à 1 500 m, sauf s’il est spécifié autrement. NOTE Pour les règles de traitement des charges de neige à des altitudes supérieures à 1 500 m, voir 6.1. (3) Le présent document ne donne pas de recommandations relatives à des aspects particuliers du chargement de neige, par exemple : - les chocs dus aux charges de neige glissant ou tombant d’une toiture plus élevée ; - les modifications de la forme ou de la dimension des ouvrages dues à la présence de neige ou de la formation de glace susceptible d'affecter l'action du vent ; - les charges de neige dans les zones où la neige est présente toute l’année ; - les charges latérales dues au fluage de la neige (par exemple, charges latérales des congères) ; - les charges dues à la neige artificielle. 1.2 Hypothèses Les hypothèses formulées dans l’EN 1990:2023, 1.2 s'appliquent.

1.1 Anwendungsbereich von EN 1991-1-3 (1) EN 1991-1-3 enthält Grundsätze und Regeln für die Bestimmung der Werte für Schneelasten, die zur Tragwerksbemessung und berechnung von Hoch- und Ingenieurbauten zu verwenden sind. (2) Dieses Dokument gilt nicht für Bauten in einer Höhenlage über 1 500 m, sofern keine anderweitigen Festlegungen getroffen wurden. ANMERKUNG Regeln für die Berücksichtigung von Schneelasten in Höhenlagen über 1 500 m sind in 6.1 enthalten. (3) Dieses Dokument macht keine Angaben über die fachlichen Aspekte von Schneelasten infolge, z. B.: - anprallender Schneelast aufgrund des Abrutschens oder Herunterfallens von Schneemassen von höheren Dächern; - Änderungen der Umrissform oder Größe von Bauwerken aufgrund von Schnee- oder Eisablagerungen, welche die Windeinwirkungen beeinflussen könnten; - Lasten in Gebieten, in denen das ganze Jahr über Schnee vorhanden ist; - seitliche Lasten aufgrund des Verformungsverhaltens von Schnee (z. B. durch Verwehungen hervorgerufene seitliche Lasten); - Lasten infolge Kunstschnee. 1.2 Annahmen Es gelten die Annahmen nach EN 1990:2023, 1.2.
