Abstract:

This paper demonstrates that the effects of the ceiling on the progress of a wall fire are quite significant, and that a project to quantify and model the effects of a ceiling on the progress of a wall fire is indeed justified. Experimental results from the open literature are used for this purpose, as well as previously-unpublished experimental results obtained at NIST. The wall-fire model SPREAD and the room-fire model FIRST are used seriatim to show that part of this effect can be calculated now.
