Abstract:
The prediction of torsional buckling of stiffeners is a necessary design skill in the planning of any framed structure or vehicle. The likelihood of torsional failure is increased when the stiffener is simultaneously loaded from perpendicular directions, a common loading condition for the frames of a ship at sea. This thesis examines first the case of a single lateral load on I beam and flat bar stiffeners and then the instance of combined lateral and axial loadings. An energy method is used and formulated are expressions for the critical buckling load for a single laterally applied force and a formula relating lateral and axial loads and giving an indication of the relative weakening of a stiffener caused by simultaneous application of both forces.
