Numerical thermal performance analysis of light steel insulated walls under fire

Light-gauge steel-framed (LSF) walls are being adopted by the Algerian construction industry as a new alternative to traditional infilled frames due advantages they provide. The strength-to-weight ratio of Cold Formed Section (CFS) leads lighter structures and decrease in building cost. However, case fire, high shape factor combined with loss material properties unprotected, slender CFS can result structural failure. Because their conductivity, elevated temperatures have an effect on thermal performance panels, necessitating use appropriate insulation. purpose this paper is perform numerical analysis behavior LSF protected plasterboard or magnesium oxide board, well cavity insulations. Numerical models developed, using ANSYS software simulate under ISO 834 fire. Thermal simulations done predict temperature profiles, maximum temperatures, estimated fire resistance level (FRL). This research has produced results better evaluate influence different systems protection insulation used for
