Research on public building fire risk assessment control model

Large space, multi-function, crowded public buildings are increasing. In case of fire, it will cause enormous casualties and property losses, so the fire control management plays an important role in the fine management of city. And the building fire risk assessment is an effective means of fire management. This article is aimed at analyzing the particularity of fire risk factors of public buildings in operational stage, and establishing the index system of fire risk assessment. This paper illustrates the fire scenario and the personnel evacuation simulation using the model of university teaching building through FDS and Pathfinder, studies about the impact on the level of building fire risk as the fire factors changing. This paper establishes the fire risk assessment model based on SVM theory, and gets a better precision in case of the small sample size, providing a new method and scientific basis for the fire risk assessment of the public buildings.
