Building fire safety evaluation method and system based on fuzzy comprehensive evaluation model

Abstract

The invention discloses a building fire safety evaluation method and system based on a fuzzy comprehensive evaluation model. The method comprises: employing building fire safety as an evaluation target to establish a hierarchic evaluation index system; according to the evaluation index system, employing a five-section partitioned computing method to perform quantitative analysis on evaluation indexes, and determining evaluation index values; grading building fire risk evaluation results, determining a safety evaluation grade set, and determining a corresponding factor set according to evaluation index influence factors; employing a hierarchic analytical method to determine the weight of each factor in the factor set; according to the weight of each factor, employing a multi-factor fuzzy comprehensive evaluation model to perform fuzzy comprehensive evaluation, and obtaining a building comprehensive fire risk belonging grade to safety evaluation grades; and employing a grade parameter evaluation method to obtain a final grade of building fire safety. The building fire safety evaluation method and system have the advantages of accuracy and comprehensiveness, and can be widely applied to the fire safety evaluation field.

Description

technical field [0001] The invention relates to the field of fire safety evaluation, in particular to a building fire safety evaluation method and system based on a fuzzy comprehensive evaluation model. Background technique [0002] Since the scale of high-rise office buildings is getting bigger and bigger, the structure is complex, and they are different in architectural form, style, function, etc., and with the application of new technologies, new materials and new building structures, the space construction area of ​​buildings is increasing. The increase in electrical equipment increases the risk of fire hazards. Modern buildings are very different from traditional buildings in terms of building materials, space size, structural form, supporting facilities, and use functions, which make their fires have the following characteristics: the fire is rapid and spreads rapidly; the interior of the building is complicated, and it is difficult to evacuate people; Rescue is diffi...
