Eurocode 3 - Design of steel structures - Part 4-1: Silos

Complementary to Part 1. Varied general rules and additional detailed rules for the structural design of free standing or supported steel silos of circular or rectangular plan for storing bulk granular solids.

Eurocode 3 - Bemessung und Konstruktion von Stahlbauten - Teil 4-1: Silos

Eurocode 3 - Calcul des structures en acier - Partie 4-1: Silos

Les Etats Membres de l'UE et de l'AELE reconnaissent que les Eurocodes servent de documents de référence pour les usages suivants :
   comme moyen de prouver la conformité des bâtiments et des ouvrages de génie civil aux exigences essentielles de la Directive du Conseil 89/106/CEE, en particulier à l'Exigence Essentielle N°1  Stabilité et résistance mécanique  et à l'Exigence Essentielle N°2  Sécurité en cas d'incendie ;
   comme base de spécification des contrats pour les travaux de construction et les services techniques associés ;
   comme cadre d'établissement de spécifications techniques harmonisées pour les produits de construction (EN et ATE).
Les Eurocodes, dans la mesure où ils concernent les ouvrages eux-mêmes, ont une relation directe avec les Documents Interprétatifs ) bien qu'ils soient d'une nature différente de celle des normes harmonisées de produits ). En conséquence, les aspects techniques résultant des travaux effectués pour les Eurocodes nécessitent d'être pris en considération de façon adéquate par les Comités techniques du CEN et/ou les groupes de travail de l'EOTA travaillant sur les normes de produits en vue de parvenir à une complète compatibilité de ces spécifications techniques avec les Eurocodes.
Les normes Eurocodes fournissent des règles de conception structurale communes d’usage quotidien pour le calcul des structures entières et des produits composants de nature traditionnelle ou innovatrice. Les formes de construction ou les conceptions inhabituelles ne sont pas spécifiquement couvertes, et il appartiendra en ces cas au concepteur de se procurer des bases spécialisées supplémentaires.

Evrokod 3: Projektiranje jeklenih konstrukcij - 4-1.del: Silosi

Dodatek k delu 1. Različna splošna pravila in dodatna podrobna pravila za konstrukcijsko zasnovo prosto stoječih ali podprtih jeklenih silosov z okroglim ali pravokotnim tlorisom za shranjevanje surovih razsutih snovi v zrnih.
