    Publication . Regaig, Rami; Piloto, P.A.G.
    This study looks at the fire insulation performance of non-load bearing light steel frame (LSF) walls, which are critical for guaranteeing the safety and resilience of modern building constructions. Understanding the behavior of LSF systems under fire circumstances is critical as they become more widely used in construction. The study process comprises the evaluation of experimental testing of several LSF wall constructions under common fire scenarios, followed by a thorough examination of thermal performance, structural integrity, and fire resistance ratings. The results show that LSF walls have promising fire insulation qualities, with insulating material, wall assembly design, and fastening techniques all having a major impact on performance. Furthermore, the findings emphasize the necessity of suitable installation techniques and fire-rated materials in improving the overall fire resistance of LSF wall systems. These ideas help to advance construction. These findings help advance building design methods, code development, and fire safety standards in the construction sector, eventually fostering the production of more resilient and secure built environments. A numerical model was developed to validate the full-scale fire test results. The insulation criterion, defined by the average or maximum temperature on the unexposed side of the wall, was evaluated. Additionally, 2D numerical analyses explored the thermal effects of cavity size and protection layers. The research highlights the impact of cavity insulation and offers insights into enhancing fire resistance for LSF walls. ANSYS Multiphysics software is used for numerical validation and parametric analysis, demonstrating the influence of structural stud spacing, cavity thickness and protective layers. The results indicate that cavity insulation has the largest impact on fire resistance for insulation, followed by increasing the number of gypsum plasterboards in the protective layer. Reducing stud spacing in walls and increasing the cavity thickness improves the fire resistance
