Steel static storage systems - Adjustable pallet racking systems - Principles for seismic design

This European Standard specifies the structural design requirements applicable to all types of adjustable pallet racking systems fabricated from steel members, intended for storage of unit loads and subject to seismic actions.
This European Standard gives also guidelines for the design of clad rack buildings in seismic zones, where requirements are not covered in the EN 1998 series.
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.
This European Standard does not apply to the design of seismic isolated racking structures.

La présente Norme européenne spécifie les exigences de calcul des structures, applicables à tous les types de systèmes de rayonnages à palettes réglables fabriqués à partir d’éléments en acier, destinés au stockage d'unités de charge et soumis à des actions sismiques.
La présente Norme européenne donne les lignes directrices pour le calcul des bâtiments de stockage en tôle plaquée situés en zones sismiques dont les exigences ne sont pas couvertes par la série EN 1998.
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 et en porte-à-faux, ni aux systèmes de rayonnages à tablettes statiques en acier.
La présente Norme européenne ne s'applique pas au calcul des structures de rayonnages parasismiques.

Stabilni jekleni sistemi za skladiščenje - Sistemi za nastavljive regale za palete - Načela potresno varnega projektiranja

Ta evropski standard določa zahteve za projektiranje konstrukcij, ki se uporabljajo za vse vrste sistemov za nastavljive regale za palete, izdelane iz jeklenih elementov, ki so namenjeni za skladiščenje tovornih enot in izpostavljeni potresnim vplivom.
Ta evropski standard podaja smernice, ki se uporabljajo za projektiranje objektov s platiranimi regali v potresnih območjih in v primerih, ko zahteve niso zajete v standardu EN 1998.
Ta evropski standard ne zajema drugih splošnih vrst skladiščnih struktur. Ta evropski standard se natančneje ne uporablja za premične sisteme za skladiščenje, vstopne, prehodne in konzolne regale ali stabilne jeklene sisteme polic.
Ta evropski standard se ne uporablja za projektiranje struktur z regali, izoliranih pred potresnimi vplivi.
