| Abstract | The experiments conducted using the test assemblies with regular gypsum board protection exhibited the same chronological sequence of fire events - fire initiation, smoke alarm activation, onset of untenable conditions, and finally structural failure of the test assemblies. The sequence was the same between the experiments conducted in this series of the full-scale fire experiments and also the same as the experiments conducted in Phase 1 of the FPH research for the fire scenario with an open basement doorway. Smoke obscuration was the first hazard to arise. Untenable (incapacitation) conditions were reached shortly after smoke obscuration. Compared to the experiments conducted in Phase 1 using the same floor structures without gypsum board protection, the times during which tenable conditions were maintained were similar or improved slightly whilst the structural performance was improved significantly with the gypsum-board-protected ceiling/floor assemblies. The times taken to reach structural failure for the gypsum-board-protected assemblies were much longer than those Phase 1 experiments with no protection. Also, with regular gypsum board protection, all test assemblies provided similar durations of structural fire endurance under the test fire scenario. |
