EN 1993-1-5 gives design requirements o f stiffened and u nstiffened plates which are subject t o inplane forces.

(1) EN1993‑1‑5 gives design requirements of stiffened and unstiffened plates which are subject to in-plane forces. (2) 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 EN1993‑1‑1. 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 EN1993‑2 and EN1993‑6. 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 EN1993‑2 and EN1993‑1‑7. NOTE 4: Single plate elements may be considered as flat where the curvature radius r satisfies: (1.1) where a is the panel width t is the plate thickness
