Abstract

The invention discloses a high-rise building fire risk assessment method, and the method comprises the steps: carrying out the primary selection of high-rise building electrical fire risk assessment parameter indexes, and obtaining primary selection system indexes; based on an FP-Growth algorithm and in combination with an association rule of a minimum threshold mining index, performing association analysis and structure optimization on the primary system index, and constructing a risk assessment index system; in combination with an index weight assignment method of improved DEMATEL-ANP, weight assignment is carried out on each index; quantifying each characteristic parameter index in risk assessment through a cloud theory model, and constructing a risk assessment matrix; and calculating the index weight of the high-rise building fire and the risk assessment matrix according to standardized weighted average, calculating the asymmetric close degree of each evaluation grade, and giving a high-rise building electrical fire risk assessment result. According to the method, the problem of effectiveness caused by only utilizing the maximum membership principle is comprehensively considered, and the accuracy and applicability of high-rise building electrical fire risk assessment are improved.

Description

technical field [0001] The invention relates to the field of high-rise building electrical fire risk identification, in particular to a high-rise building fire risk assessment method. Background technique [0002] With the development of my country's economic level, there are more and more densely populated high-rise buildings, and the social electricity consumption continues to rise, and the security risks that follow are increasing year by year. According to the statistics of the China Fire Protection Yearbook, as of 2020, from the analysis of the causes of electrical fires, 68.9% of the total are caused by circuit problems such as short circuit, overload, and poor contact, and 26.2% of the total are caused by equipment problems such as failures and improper use. %, other electrical reasons accounted for 4.9%; a total of 109,000 residential fires occurred throughout the year, accounting for 43.4% of the total number of fires. Therefore, it is particularly important to stu...
