| Abstract | This paper presents an analytical thermal-structural model for loadbearing lightweight steel framed (LSF) walls exposed to fire on one side. The model reflects temperature and deformation data from six standard fire resistance tests conducted recently by the National Research Council of Canada in partnership with the North American steel industry. Some characteristic patterns in thermal transmission and structural behaviour are discussed. Temperature histories across LSF assemblies are simulated numerically by explicit integration of transient heat transfer equations. The apparent thermal properties are calibrated for gypsum board and three types of insulation. Analytical procedures are presented to simulate lateral deformation histories and predict structural failure times. The model illustrates how different heating regimes in cold formed steel studs cause different structural failure modes. |
