The possibility of having, in parts 1-1 and 1-2 of Eurocode 3, the same approach for the design of beam-columns andfor lateral–torsional buckling, was investigated by the authors in previous papers using a numerical approach, where itwas concluded that those assumptions could be made.In the present paper, a new approach for lateral–torsional buckling has been used with the formulae for the design ofbeam-columns at elevated temperature based on prEN 1993-1-1 combined with the formulae from prEN 1993-1-2. Inboth cases the results obtained are much better than the current design expressions, when compared with those obtainedin the numerical calculations.
