Existing building fire safety assessment method

Abstract

The invention discloses an existing building fire safety assessment method, assessment indexes are quantized through index weight calculation and index score processing, the index weight calculation adopts an analytic hierarchy process, the index score processing adopts data acquisition and nondimensionalization, statistics is performed on expert scoring data through a fuzzy set valued method, and the fire safety level is obtained by using the constructed evaluation index system. The data is collected by means of platform import, field collection, data interface access and the like, the data comprises all information related to the area and the fire safety level of the existing building in the area, and the collected data and the collection method are more comprehensive; the index weight also pays more attention to the characteristics of different types of existing buildings, and the weight analysis is more targeted. The fire hazard can be intelligently identified according to different types of existing buildings and areas, and the fire safety levels of the different types of existing buildings and areas are comprehensively judged by combining factors of fire-fighting equipment, rescue, management and the like.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to an evaluation method for fire safety of existing buildings. Background technique [0002] With the continuous improvement of my country's urbanization level, the construction industry has developed rapidly. In recent years, many large-scale and new special buildings have been increasing, such as super high-rise buildings, Olympic venues, large shopping malls, underground public buildings, commercial complexes, etc. The structural forms of these buildings and the composition of combustibles are very different from what happened before. Large changes, there are greater fire safety hazards. However, with the increase in the use time of houses and buildings, many buildings have problems such as insufficient fire-fighting facilities, lack of fire-fighting water sources, and chaotic fire-fighting management. Many enterprises and units seriously neglect the fire safety work of...

Problems solved by technology

[0010] (2) Data application is not sufficient

[0011] The current "smart firefighting" platform collects data mainly for the maintenance of firefighting facilities and equipment, firefighting and rescue operation command, etc., uses the data to intelligently identify fire hazards, rectify and track them, and comprehensively analyze fire safety in existing buildings and regions Evaluation and other work have not been carried out, and data utilization is not sufficient

[0012] (3) Evaluation object is single

[0013] The current "smart fire protection" platform mainly supervises single functional areas such as urban complexes, industrial parks, and urban villages. A comprehensive platform for all functional areas has not been developed, and the evaluation object is single

[0014] (4) The evaluation method is complex

[0015] At present, most of the current semi-quantitative assessment methods of fire risk in my country are relatively complicated and involve a relatively complicated theoretical basis. Some models need to introduce a lot of calculations in the process of qualitative and quantitative transformation. For the fire risk assessment of existing buildings, the implementation of more difficult
