| dc.description.abstract | This paper investigates the behavior of load-bearing Light Steel Frame (LSF) walls under fire conditions to determine their critical temperature. LSF walls are increasingly used in sustainable building construction. The study compares experimental results from full-scale tests with a 3D numerical model developed to replicate the structural performance under fire. Three test specimens were analyzed: a smaller one (3x1 m) for load capacity at room temperature, and two larger specimens (3x3 m) tested at 84% and 27% of their load capacity. The 3D numerical analysis involved four simulations: (1) unit load to identify instability and critical loads, (2) geometrical and material nonlinear analysis with imperfections for room temperature capacity, (3) transient thermal analysis to determine temperature over time, and (4) thermomechanical analysis under constant load to assess critical temperature and fire resistance. Model validation was conducted by comparing experimental and numerical results, with Root Mean Square Error (RMSE) used to quantify temperature differences; RMSE below 100°C indicated good agreement. Results demonstrate that numerical simulations reliably predict load capacity, temperature evolution, and critical temperatures, providing a cost-effective alternative to experimental testing. | eng |
