Abstract
The paper presents a method of solving the problem of optimally designing mulli-purpose tie-beams. The problem is that of minimizing the maximum deflection of a simply supported beam under transverse load. The volume of the beam is prescribed and the maximum allowable longitudinal elongation if the beam were to act as a tie is given. The method of solution presented herein makes use of numerical optimization techniques to obtain a design satisfying specified criteria. The solutions thus obtained are compared with the results of others to show the effectiveness and usefulness of the method of solution presented herein.
