This paper presents results from numerical studies on the behavior of fire exposed steel beams by taking into consideration temperature-induced sectional instabilities. A threedimensional nonlinear finite element model is developed to evaluate the response of fire exposed steel beams under both flexural and shear effects. This model is applied to investigate the effect of sectional slenderness on the onset of local instability and capacity degradation in steel beams exposed to fire. Results from finite element analyses are utilized to evaluate failure of beams under different limit states including flexure, shear, sectional instability and deflection criteria. These results show that under certain loading scenarios and sectional configurations, shear capacity in steel beams can degrade at a higher pace than that of moment capacity. In addition, results from numerical studies infer that room temperature classification of steel beams based on local stability, can change with fire exposure time; a compact section at ambient conditions can transform to a non-compact/slender section under high temperature effects. This can induce temperature-induced local buckling in steel sections and lead to failure prior to attainment of failure under flexural yield and/or shear limit state.

“…In addition, Selamet and Garlock [8] compared the behavior of different types of partially restrained steel connections (shear tab, single angle, and double angle) in fire using finite element analysis and showed that double angle connections exhibited the most ductile behavior. They also showed that the rate of heating and cooling during a fire could affect the beam stress distribution, peak temperatures, and peak displacements but not the peak axial force [9]. More recently, Pakala et al [10], and Kodur et al [11] conducted experimental and computational investigations aiming at understanding the effect of the load level, fire scenario and composite action of the steel-concrete beam/slab assembly on the behavior of double angle connections during a fire.…”

“…The influence of such realistic fire scenarios on the behavior of structural components is a key issue in the performance-based approach, as shown for example for concrete-filled hollow structural section columns [7] or for single-plate shear connections in which the tensile forces created during the cooling phase can lead to failure [8]. The required duration of stability may be longer than the duration of the heating phase.…”
