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 Tests UF-06, UF-06R and UF-06RR carried out in the test house with unprotected wood I-joist B floor/ceiling assemblies 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 tests such as temperatures, smoke alarm activation times, smoke optical density, floor deflection and concentrations of CO, CO2 and O2. For these three tests, untenable conditions on the upper storeys were reached before structural failure of the test floor assemblies. The test results show good repeatability.
