AbstractThis paper presents the effect of various factors on the fire resistance of load-bearing, gypsum board protected, steel stud wall assemblies. A detailed experimental study was conducted to evaluate the fire resistance of 14 full-scale steel stud wall assemblies. Both single row and double row steel stud configurations with installation of gypsum board on each of the exposed and unexposed sides, and with and without insulation in the cavity, were considered in the experimental program. The insulation used were glass, rock and dry blown cellulose fibers. Data from the experimental program are used to determine the effects of stud-spacing, shear membrane, load intensity, resilient channel installation, insulation type and gauge thickness of studs on the fire resistance of gypsum board-protected, steel stud wall assemblies. Results from the studies show that the insulation type and number of gypsum board layers have significant influence on the fire resistance of steel stud wall assemblies.
