Fuzzy Comprehensive Evaluation of Fire Risk on High-Rise Buildings

According to the character of the high-rise buildings fire risk, this paper establishes the index system of fire risk on high-rise building, calculates the weight of every index by AHP, applies fuzzy pattern recognition model with the least summation of weighted generalized distance in fuzzy comprehensive assessment, sets up the fire risk assessment model of high-rise buildings based on the fuzzy pattern recognition and brings in fuzzy characteristic quantity of safety grade to deal with the assessment result of fire risk on high-rise building. At last, this method stated above is applied to some hotel in Xi’an which can provide available gist for performance-based fire protection design and safety management.
