Abstract: In order to improve the level of fire safety, enhance the capacity for disaster prevention and emergency response and reduce the disaster losses caused by fire accidents, factors affecting community vulnerability to fire were identified firstly from the following four aspects: demographic characteristics, community management, physical factors and resilience. An evaluation index system was established for community vulnerability to fire based the factors and a projection pursuit model was constructed to calculate the weights of different vulnerability factors. Finally, the model was applied to 104 communities in the case of Yangjing, Shanghai. The results show that old communities with aged residents, have the highest level of vulnerability to fire, and need to be focused particularly, that the low-rise communities have a higher level of vulnerability than the high and middle-risecommunities, and that physical elements in community have a great impact on the level of community vulnerability.
