This study evaluates the accuracy of the finite element method (FEM) as a tool for post-fire forensic assessment of reinforced concrete members. Numerical simulations were conducted to model reinforced concrete beam specimens after fire exposure, using data from a previous experimental study. The analysis focused on comparing experimental and numerical load–deflection responses. The simulation results showed good agreement with the experimental behavior. The error in deflection at the maximum-load point was 0.009% for beam A0 and 1.02% for beam A7. Compared with A0, the fire-exposed beam (A7) exhibited a 5.08% reduction in load-carrying capacity and an 18.58% decrease in maximum deflection. Overall, the findings confirm that FEM can effectively support forensic evaluation of fire-induced damage in reinforced concrete beams.References
