- Abstract
- The purpose of this thesis is to demonstrate and enhance the technical basis of the procedure for evaluating lifesafety within the Building Firesafety Engineering Method (BFSEM). A framework for the analysis has been documented, but not extensively tested in a building situation. Hence, procedures to obtain the necessary input data and to evaluate that data needed to be developed. In addition, the general framework had to be tested rigorously enough to identify weaknesses. Evaluating lifesafety in the BFSEM combines both people movement and smoke movement analyses. The lifesafety analysis in the BFSEM is quite different from traditional code approaches. Codes typically deal with designing exits for the building occupants. Time is implicit in the code approach. The BFSEM, on the other hand, attempts to idenfity the performance of the egress system for exptected fires in the building. The method attempts to predict whether egressing people and hazardous conditions will occupy the same space at the same time. One of the goals of this thesis is to define "hazardous conditions".
