Abstract

THE simplified method of stressing which follows is an extension of one first developed as a means of attacking the shear‐lag prob‐lem for a ship‐beam (Trans. N.E. Coast Inst, of Engrs., 1924–5). It is now extended to cover also axial stresses due to torsion and departure from the Batho torsion shear, a related subject. Shear‐lag and diffusion are closely connected and a theory which covers one should have at any rate a general application to the other; it is not, how‐ever, claimed for the present method that it is very suitable for use where the rates of diffusion are locally high, and its applicability to diffusion problems in general is a matter of judgment.This of course applies also to any corresponding method. The method is considered first for a girder of uniform transverse dimensions (no taper of depth or width) but with variation in scantlings along its length. Later the first‐order effect of tapered dimensions is considered. There may be longitudinal stiffeners at any point in the section, e.g. spar booms or stringers. The transverse sections of the girder are assumed to retain their dimensions with absolute rigidity.
