Temperature field modeling of the first Cardington test

Results of heat transfer numerical simulations, using SAFIR program, for the composite floor beam of the first Cardington fire test in the eight-story steel-framed building are presented. For steel beam temperature predictions, the 2D mesh model was simplified by neglecting the presence of the steel deck and averaging the concrete slab thickness. This model was sufficient to yield a satisfactory match of predicted and measured temperatures in the steel beam. The predictions show that the unprotected bottom flange and web temperatures follow closely the temperature of the fire gas environment

Fire Resistance Performance of Lightweight Framed

The paper presents the effects of a number of design parameters investigated by the authors including the types of cavity insulation, resilient channels, gypsum board thickness, number of gypsum board layers, stud arrangements, stud spacing, type of framing and shear membrane. The results have shown that the main factors that affected the performance of stud wall assemblies were the type of insulation, stud spacing, the number of gypsum board layers, and the addition of a shear membrane. The paper will also describe how the information gathered from this study will be used to benefit practitioners, builders and regulators in choosing suitable assemblies for their designs
