- Abstract
- This thesis presents a deterministic method for tracking smoke movement through multi-coimpartment, multi-floor structures based on a unit mass of smoke, called a smoke tracking unit (STU). This method allows the engineer to track the obscuration, temperature, and height of the hot upper smoke layer as the smoke moves through compartments, into stairwells, to upper floors, and to the outside of the building. Probability of maintaining tenability curves are constructed based on the results of the deterministic analysis and are used to evaluate the tenability in a target space. The uncertainties introduced in the deterministic analysis are accounted for in the probabilistic evaluation. This method is then used as part of the Building Firesafety Engineering Method (BFSEM) evaluation of the test building used in the CIB/W14 firesafety symposium and workshop held at the University of Ulster, Northern Ireland in September 1993.
