This paper by P M M Vila Real was published in the Journal of Constructional Steel Research, Volume 64 Issue 11, November 2008. It describes a numerical study on the behaviour of stainless steel I beams subjected to lateral torsional buckling in case of fire. Comparisons are made with the beam design curves found in Eurocode 3. Following this comparison, new formulae for lateral torsional buckling that better approximate the material behaviour, are proposed. These formulae are based on simulations using the program SAFIR, which was modified to take into account the material properties of stainless steel.
