Two fire zone models CFAST 2.0 and BRI2T are applied to simulate fires
in multi-level apartments. Apartments with different levels and sever
al compartments including a staircase are taken as examples. Smoke con
trol designs including ceiling vents and smoke extraction systems inst
alled in the staircase are considered with their performance evaluated
. Experimental results reported in the literature are used to compare
with the predicted results.
