Abstract(s)
The possibility of having, in parts 1-1 and 1-2 of Eurocode 3, the same approach for the design of beam-columns and
for lateral–torsional buckling, was investigated by the authors in previous papers using a numerical approach, where it
was 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 of
beam-columns at elevated temperature based on prEN 1993-1-1 combined with the formulae from prEN 1993-1-2. In
both cases the results obtained are much better than the current design expressions, when compared with those obtained
in the numerical calculations.
