AbstractThis paper addresses the structural behaviour of cold-formed steel members subjected to axial compression and severe heating. Analytical approaches used in retrospective numerical simulations of fire resistance tests are discussed. The developed model reflects the structural failure modes observed in the experiments and gives appropriate consideration to thermally-induced stresses and deformations. The behaviour of loaded steel studs is shown to be sensitive to structural boundary conditions and non-uniform heating. The numerical techniques are described in detail and demonstrated in lateral deflection simulations. The model produces structural failure time (fire resistance) predictions that are consistent with experimental data.
