DANSK DS/EN 1993-1-5 PDF

(1) EN 1993-1-5 gives design requirements of stiffened and unstiffened plates which are subject to inplane 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 EN 993-1-1. 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. NOTE 4: Single plate elements may be considered as flat where the curvature radius r satisfies: t a r 2³ (1.1) where a is the panel width t is the plate thickness.
