Abstract
When a beam is bent about its greatest flexural resistance axis it may twist and move laterally, before it reaches its strength limit. Although this problem of lateral torsional buckling of steel beams at room temperature is well known, the same problem at elevated temperature is not. This paper summarises the results obtained in the scope of a research project entitled Lateral buckling of steel I beams under fire conditions, where a set of 120 experimental and numerical tests were performed on IPElOO beams, submitted to temperatures varying from 20 C to 600 C, to validate a new proposal for the buckling resistance moment of a laterally unrestrained beam under fire conditions. It will be shown that this new proposal is safer than the Eurocode 3 formulas.
