STUDY ON NATURAL SMOKE EXHAUSTION IN BUILDINGS WITH LARGE CAVITY SPACE

This study investigates the characteristics of natural smoke exhaustion in the case of fire in buildings with a large cavity space. If the cavity space area is large enough, it can be considered equivalent to the ambient space. Therefore, it becomes possible to discharge the smoke at the time of fir...
