Abstract
The problem of shear lag is tackled by means of a classical technique which, in its present form, appears
to offer a simpler and more direct approach, yielding a closed-form solution for the longitudinal stress
distribution in wide flanges of box girders and ensuing effective - breadth ratios. The method is
particularly suited to parametric studies and a number of these are undertaken both for purposes of
computational illustration and so as to study cases of practical relevance. Some of the salient features
in the latter are highlighted, especially as an aid to engineers at the preliminary design stage of
plated structures.
