Steel static storage systems - Adjustable pallet racking systems - Principles for structural design
This European Standard specifies the structural design requirements applicable to all types of adjustable beam pallet rack systems fabricated from steel members intended for the storage of unit loads and subject to predominantly static loads. Both un-braced and braced systems are included.
This European Standard gives guidelines for the design of clad rack buildings where requirements are not covered in EN 1993. The requirements of this European Standard also apply to ancillary structures, where rack components are employed as the main structural members.
This European Standard does not cover other generic types of storage structures. Specifically, this European Standard does not apply to mobile storage systems, drive-in, drive-through and cantilever racks or static steel shelving systems, nor does this European Standard establish specific design rules for the assessment of racking in seismic areas.
Ortsfeste Regalsysteme aus Stahl - Verstellbare Palettenregale - Grundlagen der statischen Bemessung
Diese Europäische Norm legt die Anforderungen für sämtliche Arten von Palettenregalen mit verstellbaren Trägern fest, welche aus Stahlelementen hergestellt und zur Lagerung von Lasteinheiten vorgesehen und vorwiegend statischen Lasten ausgesetzt sind. Sowohl Systeme mit als auch ohne Aussteifungsverbände sind berücksichtigt.
Die Anforderungen gelten auch für Zusatzeinrichtungen, bei denen Regalbauteile als wichtiges Hauptbauteil eingesetzt sind.
Diese Norm gilt nicht für andere Arten von Lagereinrichtungen, namentlich nicht für Verschieberegalsysteme, Einfahr- und Durchfahrregale, Kragarmregale und Fachbodenregale aus Stahl.
Palettenregale sind gewöhnlich Serienprodukte, bei denen eine Auslegung aus¬schließlich nach Berechnung ggf. nicht angebracht ist. Aus diesem Grund werden Versuchsverfahren vorgeschrieben, wo zzt. analytische Methoden nicht verfügbar oder nicht anwendbar sind. Die entsprechenden Versuchsverfahren sind in Anhang A dargestellt.
Systèmes de stockage en acier - Systèmes de rayonnages à palettes réglables - Principes applicables au calcul des structures
La présente Norme européenne spécifie les exigences applicables à tous les types de systèmes de
rayonnages à palettes réglables fabriqués à partir d'éléments en acier, destinés au stockage de charges
unitaires et soumis à des charges essentiellement statiques. Les systèmes non contreventés et contreventés
sont inclus.
Les exigences s'appliquent également aux structures annexes lorsque des éléments de rayonnages sont
employés comme éléments structuraux.
La présente norme ne couvre pas les autres types génériques de structures de stockage. En particulier, elle
ne s'applique pas aux systèmes de stockage mobiles, aux systèmes de rayonnages à accumulation statique
et en porte-à-faux, ni aux systèmes de rayonnages à tablettes statiques en acier.
Les rayonnages à palettes sont des produits normalisés pour lesquels une conception par calcul seul peut ne pas
être appropriée. Des méthodes d'essai sont donc spécifiées lorsque les méthodes d'analyse courantes ne sont
pas indiquées ou s'avèrent inappropriées. Les méthodes d'essais appropriées sont données à l'Annexe A.
