Fire Performance of Selected Residential Floor Constructions Under Room Burnout Conditions
A series of seven large-scale room burnout fire tests was conducted with a set of selected residential floor-ceiling assemblies to provide data on the performance of the assemblies; these will be compared with the results in future tests on the same constructions in a fire endurance furnace. Four wood-frame and three light gage steel-frame, load-bearing assemblies, each measuring 3.7 x 3.7 m in size, were exposed from the underside to a fire environment produced from the burning of typical furniture and interior finish materials in a room. The fire resistance periods based on flame-through of floor assembly and structural failure of floor joists varied from 10 to 12 minutes for floors with unprotected wood joists and was 4 minutes or less for floors with unprotected steel joists. The addition of a 12.7 mm thick gypsum board ceiling as a protective layer increased the fire resistance time of the steel joisted floor assembly approximately 12 minutes.
