Experimental and thermal analysis of wall assemblies exposed to standard and parametric fires

Abstract
The aim of this study is to assess the effect that different fire exposures have on the behaviour of gypsum plasterboard assemblies with known fire resistance rating. For this purpose a series of fire tests were performed on commonly used wall assemblies. Four different small scale samples were tested under ISO 834 and HCC standard fire curves. Additionally, one assembly was tested in an enclosure, with a pool fire used as a heat source. The results show that although there is a higher temperature exposure in HCC, the time criterion for standard classification is fulfilled in the small scale tests. A steeper rise of the temperature on the unexposed side for the HCC appears after 65 minutes in the worst case. In the pool fire test the... (More)

The results show that although there is a higher temperature exposure in HCC, the time criterion for standard classification is fulfilled in the small scale tests. A steeper rise of the temperature on the unexposed side for the HCC appears after 65 minutes in the worst case. In the pool fire test the highest temperature values measured on the unexposed side are closer to the values obtained in the HCC test, while the lower are below the ISO 834 results. 2D-heat transfer analysis was conducted on one of the assemblies tested. The aim was to evaluate if empirical thermal properties commonly assumed to model ISO 834 fire exposures are adequate for modelling other temperature-time exposures. The results show a need of further investigation on the thermal properties. (Less)
