Research on fire-safety assessment of high-rise building based on the fuzzy centralization theory

High-rise building has greater risk of fire according to its features such as great height, complex structure and diverse functions and so on. It´s easy to cause heavy casualties and property losses once the high-rise building fire taking place. It´s of great significance, through the fire-safety evaluation for high-rise building, to prevent the occurrence of high-rise building fire in time. For the characteristics of high-rise building fire, the paper constructs its fire safety evaluation index system on the basis of abstract the main factors which influence the high-rise building fire-safety. And to determine the weights of indicators through experts´evaluation and points-scoring, fuzzy computing and other methods, then to calculate the assessment level of high-rise building fire-safety by using the fuzzy centralization theory. Exemplified case study has shown that the method could overcome the shortage of traditional statistical method, the evaluation result is in line with the actual situation, and with the strong operability and practical values.
