Resumo(s)
Stainless steel structures are increasingly used in civil engineering due to their mechanical strength and corrosion resistance. However, under fire conditions, their performance may degrade significantly. This study investigates the fire resistance of austenitic 1.4301 stainless steel beams using finite element simulations in ANSYS. A parametric analysis was performed considering seven different rectangular hollow sections, exposed to ISO 834 fire conditions on and subjected to bending. Geometrically and materially nonlinear analysis (GMNIA) was applied to evaluate thermal and mechanical responses. The results indicate that section geometry, especially thickness and width, significantly influences both temperature distribution and structural performance during fire exposure. Beams with greater thickness exhibited lower internal temperatures and improved fire resistance times. These findings support the optimization of stainless steel beam designs for enhanced fire safety.
