Abstract
Smoke control in il space 10 m${\times}$3 m floor and 5.4 m high around the stairway of a subway station platform was simulated by using FDS to investigate problems of smoke control in Daegue subway stations. Distributions of temperature and smoke particles, and variation of the number of particles with time for a 200 ㎾ polyurethane fire were compared. It was shown that the purge system fails to remove smoke efficiently and that the extraction system has the highest perfor-mance among the three smoke control systems for the given situations. Simply switching the purge system into extraction mode might improve much the smoke removal performance.
