dc.description.abstractWhen a beam is bent about its greatest flexural resistance axis it may twist and move laterally, before it reaches its strength limit in bending. Although this problem of lateral-torsional buckling of steel beams at room temperature has well established solution, the same problem at elevated temperature has not. The lateral-torsional buckling of steel I- beams have been numerically investigated from room temperature up to 700 °C, with the aim of assessing the effects of the residual stresses in this mechanism of failure. A geometrically and materially non-linear finite element program i.e., a general model, has been used to determine the lateral-torsional resistance of steel 1-beams at elevated temperatures, according to the same material properties of Eurocode 3, Pan 1-2. The numerical results have been compared to the results of the simple model presented in Eurocode 3, Part 1-2 (1995) and to a new proposal that is being considered for approval.pt
