Fire control risk assessment method based on single building

Abstract

The invention provides a fire control risk assessment method based on a single building. The fire control risk assessment method comprises the following steps: establishing a high-rise building fire risk assessment index system; adopting a fuzzy analytic hierarchy process to form a multi-level analysis structure model according to the mutual relation and the membership relation of the first-levelindexes and the second-level indexes and different levels of aggregation and combination; performing quantitative processing according to the relative importance of the secondary indexes scored to each level by experts so as to determine weight coefficients; constructing a judgment matrix A; calculating the weight of each index according to the judgment matrix A; and carrying out consistency checkon the judgment matrix A, calculating a consistency ratio, giving an evaluation result when the consistency ratio is smaller than 0.1, and otherwise, correcting the judgment matrix A again. Accordingto the fire control risk assessment method, under the condition of fully considering various effective resources, the risk assessment of the building is more objective, fair and accurate, and meanwhile, the urban building control and risk resistance capabilities are improved by utilizing a technical means.

Description

technical field [0001] The invention belongs to the technical field of building fire protection, in particular to a fire risk assessment method based on a single building. Background technique [0002] With the rapid development of urbanization in our country, more and more high-rise buildings are emerging, and their fire safety problems are becoming increasingly prominent. A comprehensive analysis of the possible risk factors, accident occurrence rules, and hazard sources of individual buildings , will help to identify and eliminate major fire hazards. The current risk assessment of individual buildings is only carried out by the supervision and law enforcement department on the spot, and then an assessment report is issued according to the inspection situation. The assessment results are highly subjective due to the different quality of law enforcement personnel, and are relatively one-sided and lack scientificity. Contents of the invention [0003] In order to solve th...
