AbstractThis report documents part of the research project involving a series of full-scale fire experiments in a test facility that simulated a two-storey single-family house with a severe, fast growing fire originating in an unfinished basement to study the fire performance of the floor/ceiling assembly constructed over the basement. The report presents the results and analysis of Test UF-04 carried out in the test house with an unprotected steel C-joist floor/ceiling assembly above the basement with an open basement doorway (no door in the doorway leading from the first storey to the basement). A number of measurements were taken at various locations during the test such as temperatures, smoke alarm activation times, smoke optical density, floor deflection and concentrations of CO, CO2 and O2. For this test, untenable conditions on the upper storeys were reached before structural failure of the test floor assembly.
