Scope of prEN 1993-1-5

This document provides rules for structural design of stiffened and unstiffened nominally flat plates which are subject to in-plane forces.

Effects due to shear lag, in-plane load introduction and plate buckling for I-section girders and box girders are covered. Also covered are plated structural components subject to in-plane loads as in tanks and silos. 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.

Single plate elements are considered as nominally flat where the curvature radius r in the direction perpendicular to the compression satisfies:

Assumptions

Unless specifically stated, EN 1990, EN 1991 (all parts) and EN 1993-1-1 apply.

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 EN 1993 (all parts) or in the relevant material product specifications.
