The lateral torsional buckling behaviour and design of steel beams in fire are investigated in
this paper. Finite element models able to replicate the lateral-torsional buckling (LTB) …

Numerical modelling of the lateral–torsional buckling of steel beams at elevated temperature
has shown that the beam design curve from EN 1993-1-2 is over-conservative in the case of …

The behaviour of unrestrained steel I-beams has been studied by means of numerical
analysis and published experimental results. The numerical model was developed using a …

Current design approaches to assess the lateral torsional buckling capacity of steel beams
in fire are based on the assumption of uniform steel temperature. This paper investigates the …

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 …

An extensive numerical study is performed to investigate the lateral–torsional buckling of
steel beams with slender cross sections for the case of fire. The influence of local buckling is …

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 …

High strength steels are increasingly common in structural engineering applications owing
to their favourable strength to weight ratio, excellent sustainability credentials and attractive …

This paper presents the results of a numerical study, using ABAQUS, of the large deflection
behaviour of steel beams at elevated temperatures with different elastic axial and rotational …

In this paper, the effect of non-uniform bending on the lateral torsional buckling (LTB) of steel
beams with slender cross-sections subjected to elevated temperatures is numerically …
