In recent years, despite the rapid economy development in Taiwan, there still standing a lot of this kind of houses in villages and towns. Due to lack of overall rebuild plan, the inner old electric wire and the improper use of electric devices, plus narrow street sidewalks parked with cars which prevented fire engine from entering, as well as dense population and residential environment, if the fire happened, it could often cause great casualties and property losses. This paper is using an attached townhouse fire in Yangmei township in 2008 for fire study. There are too much combustibles in the fire house, and because all house additions are reconstructed with metal sheets at third floors, the fire spread out rapidly without effective isolation. This study uses Fire Dynamics Simulator (FDS) software to analyze the physical phenomenon of the fire scene and to analyze the heat conduction, smoke flows, upper layer temperature, change of carbon monoxide (CO) concentrations, and by adjusting the parameters of the key factors to analyze the influence of different conditions in fire scene. The simulation result is expected to provide a reference for fire protection engineering of the residential buildings.
