Abstract:
A gypsum wall assembly was exposed to an intense
real-scale compartment fire. For the wall assembly,
temperatures were measured at the exposed face, within
the stud cavity, and at the unexposed face during
the fire exposure. Total heat flux gauges were used to
measure the temporal variation of the energy incident
on the walls, and cameras, both visual and infrared,
were used to image the unexposed face of the wall
assembly during the fire exposure. The behaviour of the
wall assembly under the fire load is discussed as are
current model results for a simulation of the fire test.
