1.1 Scope of EN 1993-1-5
(1) This document provides rules for structural design of stiffened and unstiffened nominally flat plates which are subject to in-plane forces.
(2) Non-uniform stress distributions due to shear lag, in-plane load introduction and plate buckling are covered. The effects of out-of-plane loading are outside the scope of this document.
NOTE 1 The rules in this part complement the rules for class 1, 2, 3 and 4 sections, see EN 1993-1-1.
NOTE 2 For the design of slender plates which are subject to repeated direct stress and/or shear and also fatigue due to out-of-plane bending of plate elements ("breathing"), see EN 1993-2 and EN 1993-6.
NOTE 3 For the effects of out-of-plane loading and for the combination of in-plane effects and out-of-plane loading effects, see EN 1993-2 and EN 1993-1-7.
(3) Single plate elements are considered as nominally flat where the curvature radius r in the direction perpendicular to the compression satisfies, as illustrated in Figure 1.1:
r≥b^2/t (1.1)
b is the panel width;
t is the plate thickness.

1.2 Assumptions
(1) Unless specifically stated, EN 1990, the EN 1991 series and EN 1993-1-1 apply.
(2) The design methods given in EN 1993-1-5 are applicable if
- the execution quality is as specified in EN 1090-2 and
- the construction materials and products used are as specified in the relevant parts of the EN 1993 series or in the relevant material product specifications.
