INELASTIC BUCKLING OF STEEL BEAMS UNDER NON UNIFORM MOMENT

The influence of the conditions of loading and lateral support on the inelastic lateral buckling of rolled steel beams is studied using a finite element approach. The numerical results obtained are subsequently used to assess the accuracy of simplified methods of allowing for these factors. Changes in the form of the applied loading are found to affect the critical moment much less in the inelastic range than in the elastic range and it is therefore suggested that the use of an effective length approach provides the most appropriate method of dealing with such factors.
