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 the EN 1993 series. 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, pallet live storage, push back, shuttle systems, systems where two or more cranes operates one above another in the same aisle and cantilever racks or static steel shelving systems.
For the specific design of adjustable pallet racking for use in Seismic areas, this standard should be used in combination with EN 16681 Adjustable pallet racking systems — Principles for seismic design.
Ortsfeste Regalsysteme aus Stahl - Verstellbare Palettenregale - Grundlagen der statischen Bemessung
Diese Europäische Norm legt die Anforderungen an die statische Bemessung für sämtliche Arten von Palettenregalen mit verstellbaren Trägern fest, welche aus Stahlelementen hergestellt und zur Lagerung von Ladeeinheiten vorgesehen und vorwiegend statischen Lasten ausgesetzt sind. Sowohl Systeme mit als auch ohne Aussteifungsverbände sind berücksichtigt.
Diese Europäische Norm dient als Leitlinie zur statischen Bemessung von Gebäuden aus verkleideten Regalen, im Falle, dass deren Anforderungen nicht von der Normenreihe EN 1993 abgedeckt sind. Die Anforderungen dieser Europäischen Norm gelten auch für Zusatzeinrichtungen, bei denen Regalbauteile als wichtiges Hauptbauteil eingesetzt sind.
Diese Europäische Norm deckt keine anderen generischen Arten von Lagerstrukturen ab. Diese Europäische Norm gilt ausdrücklich nicht für Verschieberegalsysteme, Einfahr- und Durchfahrregale, Paletten-Einfahr- und -Durchlaufregale, Einschubregale, Shuttle-Systeme, Systeme, die aus zwei oder mehr RFZ bestehen, welche über einander im selben Gang arbeiten sowie Kragarmregale oder statische Regalsysteme aus Stahl.
Zur spezifischen Auslegung von verstellbaren Palettenregalen zur Verwendung in Erdbebengebieten sollte diese Norm in Kombination mit EN 16681 Ortsfeste Regalsysteme aus Stahl - Verstellbare Palettenregale - Leitsätze für die erdbebensichere Bemessung verwendet werden.
Systèmes de stockage statiques en acier - Systèmes de rayonnages à palettes réglables - Principes applicables au calcul des structures
La présente Norme européenne spécifie les exigences de calcul des structures, applicables à tous les types de systèmes de rayonnages à palettes à lisses réglables fabriqués à partir d’éléments en acier, destinés au stockage d’unités de charge et soumis à des charges essentiellement statiques. Les systèmes non contreventés et contreventés sont inclus.
La présente Norme européenne donne les lignes directrices pour le calcul des bâtiments de stockage en tôle plaquée dont les exigences ne sont pas couvertes par l'EN 1993. Les exigences de la présente Norme européenne s'appliquent également aux structures annexes lorsque des éléments de rayonnage sont employés comme éléments structurels principaux.
La présente Norme européenne ne couvre pas les autres types génériques de structures de rayonnage. En particulier, elle ne s'applique pas aux systèmes de stockage mobiles, aux systèmes de rayonnages à accumulation statique, au stockage dynamique sur palettes, aux systèmes à gravité inversée, aux systèmes à navette, aux systèmes où deux ponts roulants ou plus fonctionnent l'un au-dessus de l'autre dans la même allée, aux rayonnages en porte-à-faux, ni aux systèmes de rayonnage à tablettes statiques en acier.
Pour la conception particulière de rayonnages à palettes réglables destinés à une utilisation en zones sismiques, il convient d’utiliser la présente norme en combinaison avec l'EN 16681 Systèmes de rayonnages à tablettes ajustables - Principes pour le calcul parasismique.
