Lateral-torsional buckling of unrestrained steel beams under fire conditions: i...
Vila Real, P. M. M.; Lopes, N.; Silva, L. Simões da; Franssen, J. -M.The final draft of the EN version of part 1.1 of Eurocode 3 has introduced significant changes in the evaluation of the lateral-torsional buckling resistance of unrestrained beams at room temperature that reduce the over-conservative approach of ENV 1993-1-1 in the case of non-uniform bending. ; http://www.sciencedirect.com/science/article/B6V28-4CMYJ6V-3/1/62c8b43b1bfa9671066ce946212592b5

A new proposal of a simple model for lateral-torsional buckling of unrestrained...
Vila Real, P.M.M.; Piloto, P.A.G.; Franssen, J.-M.The behaviour of Steel I-Beams exhibiting lateral-torsional buckling at elevated temperature has been studied by means of experimental and numerical analysis. The authors in an earlier paper have presented an analytical formula for the buckling resistance moment in the fire design situation. This new proposal, different from the actual proposal of the Eurocode 3 Part 1.2 has been validated in this work by compa...
