BS EN 1993-1-5:2006 gives design requirements of stiffened and unstiffened plates which are subject to inplane 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.
