In this article, a numerical modeling for fire dynamic simulation is used to predict and compare the spreading characters of fire products (the smoke height change, the temperature distribution and the visibility change) when fires with 2.5 MW heat release rate occur in the platform center and at the platform end in the two kinds of metro stations. In Washington, D.C., the “high-dome” structure is predominant in the construction of metro stations, while in Guangzhou, most metro stations have the “flat ceiling” structure. The typical structures of metro stations in Guangzhou and Washington, D.C., are very different from each other.
Due to the variations in the design of metro stations, the hazard posed by the spreading products of the fire can pose different risks. Fire is one of the most common disasters that threaten the safety of the crowd in metro stations.
