In this study, numerical simulations were carried out to analyze the effect of the smoke extraction system and fire shutters in subway station fires using FDS 4.0. CFD validation was carried out by comparison between numerical results and experimental results. Temperature distribution under the ceiling showed a good agreement with experimental results approximately within 10°C. Numerical predictions were performed in the island-type subway station in case of a kiosk fire. Case that smoke extraction systems both the platform and the concourse were operated and fire shutters were closed was most effective on smoke control.
