A Method of Minimum Weight Design for Thin-Walled Beams

Design of any structure for minimum weight is essentially based on the determination of optimum proportions on the basis of simultaneous failure in all the critical modes. The critical modes for a thin-walled beam subjected to bending loads would be due to yielding of the extreme fibre in tension or compression and local buckling of the compression flange. S.
