AbstractIRC's Fire Risk Management Program, working with nine industry partners, conducted 14 full-scale standard tests to study the effect of various parameters on the fire resistance of load-bearing steel-stud wall assemblies. Test parameters included the spacing of steel studs; the number of stud rows (i.e., single- versus double-stud walls); the number of gypsum board layers (i.e., one versus two layers of protection); the use of cross-bracing; the replacement of one layer of gypsum board with an oriented strand board (OSB) shear membrane; the use of resilient metal channels to support the gypsum board; and the type of insulation used in the wall cavity. Each full-scale assembly was exposed to a standard fire in a propane-fired vertical furnace until it failed in one of three ways: structural failure; exceeding a specified temperature; flame or gas penetration. In all cases, the wall assemblies failed structurally. The unexposed surface temperature at this time was below the temperature criteria for failure.
