(1)P EN 1993-1-7 provides basic design rules for the structural design of unstiffened and stiffened plates
which form part of plated structures such as silos, tanks or containers, that are loaded by out of plane actions.
It is intended to be used in conjunction with EN 1993-1-1 and the relevant application standards.
(2) This document defines the design values of the resistances: the partial factor for resistances may be
taken from National Annexes of the relevant application standards. Recommended values are given in the
relevant application standards.
(3) This Standard is concerned with the requirements for design against the ultimate limit state of:
– plastic collapse;
– cyclic plasticity;
– buckling;
– fatigue.
(4) Overall equilibrium of the structure (sliding, uplifting, overturning) is not included in this Standard,
but is treated in EN 1993-1-1. Special considerations for specific applications may be found in the relevant
applications parts of EN 1993.
(5) The rules in this Standard refer to plate segments in plated structures which may be stiffened or
unstiffened. These plate segments may be individual plates or parts of a plated structure. They are loaded by
out of plane actions.
(6) For the verification of unstiffened and stiffened plated structures loaded only by in-plane effects see
EN 1993-1-5. In EN 1993-1-7 rules for the interaction between the effects of inplane and out of plane
loading are given.
(7) For the design rules for cold formed members and sheeting see EN 1993-1-3.
(8) The temperature range within which the rules of this Standard are allowed to be applied are defined in
the relevant application parts of EN 1993.
(9) The rules in this Standard refer to structures constructed in compliance with the execution
specification of EN 1090-2.
(10) Wind loading and bulk solids flow should be treated as quasi-static actions. For fatigue, the dynamic
effects must be taken into account according to EN 1993-1-9. The stress resultants arising from the dynamic
behaviour are treated in this part as quasi-static.
