The Safety Assessment Of Fire Protection In Building Based On The Theory Of Hazard

Building is the place people produce and live, having the characteristics of wealth concentration, personnel concentration and smoke spirit toxicity big, is a place fire to deliver more, result in a cluster of malignant accident that dies a group of wounds easily. This article aims at the above-mentioned problem, relevant theories and mathematics methods of the applied safety system engineering, carried on the assessment to the fire protection system of the city building, the main research contents is as follows:1. Based on the hazard theories, this article systematically analyzed the hazard within building fires, divided the hazards of the building fire into three, and process the definition, is the foundation of the full text; Based on the systematically analysis to three fire hazards, this article combined the characteristics of construct a fire occurrence development, define the fire protection system of the building; Analyze and processing the different type of building fires.2. Summing-up fire cases of countrywide cities in 2000-2003, based on the frequency of fire and FTA analysis method, this article analysis the fire protection system of the initial stage and spread stage of fire; through the count and taxis the importance of the basis events, this article found out the weakness of the fire protection system in different stages of fire.3. Based on the Fault tree analysis of different stages of building fire, this article adopt the method of the cause-effect analysis, which combine ETA (Event tree analysis) and FTA (Fault tree analysis), and bring forward the new index of evaluation; applying the theory of fuzz and adopting the method of qualitative and quantitative, this article found a model of fuzz-evaluation of fire hazard; finally, take a business building in Ji-Nan for demonstration example.4.Through the actuality analysis of fire protection system of building in china, combining the design target of fire protection system, this article define the different stages of fire...
