(1) EN 199315 gives design requirements of stiffened and unstiffened plates which are subject to inplane forces.
(2) Effects due to shear lag, inplane load introduction and plate buckling for Isection girders and box girders are covered. Also covered are plated structural components subject to in[r]
(1) EN 199319 gives methods for the assessment of fatigue resistance of members, connections and joints subjected to fatigue loading.
(2) These methods are derived from fatigue tests with large scale specimens, that include effects of geometrical and structural imperfections from material product[r]
It is not possible in the rolling process to produce sections to the exactdimensions specified. For various reasons, including roller wear, the elementsof the cross-section (flanges and webs of I- and H-sections, legs of angles,etc.) may be slightly thicker than desired or may not be exactly at righ[r]
