AbstractThis paper deals with the performance of smoke shafts in reducing both the level of smoke concentration in the fire floor and smoke transfer to other floors. By reducing the pressure in the fire floor relative to other floors, a smoke shaft can induce air flow across the fire floor enclosure into the fire floor and out through the smoke shaft. In this way, the spread of smoke into vertical shafts and upper floors is prevented. If windows on a fire floor are broken, however, pressure in the fire floor approaches that of the outside and smoke shafts are no longer effective. A smoke- proof tower for interior stairwells can be effective for most cases in preventing contamination of stairwell shafts in the event of fire.
