Research On Fire Risk Assessment And Safety Management Methods Of Public Building

On the basic of the fire risk assessment theory of public buildings,the paper researches the fire risk assessment and safety management practices.The study was divided into design phase,construction phase and use maintenance phase.The main contents are the following:1.The basic fire risk assessment theory of public building was discussed and researched.Firstly,in accordance with the concepts of life-cycle construction projects and fire safety management features,the paper points out the whole life fire life safety management can be divided into the design stage,construction stage,the use maintenance phase,and analyzes various stages of the main body of fire safety management,mission objectives and content differences.On the basis of summing up the public building fire characteristics,the paper puts forward the concept of public building fire risk based on the dangerous source,and describes their contents.The composition of building fire risk costs is studied,and puts up cost and risk researches.By the differences of analyzing the whole fire safety management at all stages of life evaluation in the target system,the paper constructs the multi-index system of risk assessment with the design phase,the construction phase and the use maintenance phase.By the classification methods to fire risk accident results and fire risk probability,the paper makes researches and comes to the building fire risk matrix,and analyzes the regional corresponding fire risk level.2.The paper puts up a design-stage fire risk assessment model of public building based on Fuzzy Petri Net(FPN)Firstly,the paper introduces the basic theory of performance-based fire prevention methods,performance-based fire analysis of the content,fire risk assessment framework basic assumptions and theories with design phase.The paper puts up the performance-based fire design of concrete results,points out their results still be fire risk and need for fire risk assessment.For the risk assessment diversification,the paper puts up a building risk assessment models based on the FPN theories,and discusses the basic algorithm of the model.At the same time,using the FPN model,the papers carry out a risk assessment program researches for a community of Xi'an supporting affordable housing General commercial building.3.The fire fault tree of public building in the construction phase is set up,and carries out qualitative analysisBased part of the construction site for the fires accidents occurred in 2007,the paper introduces the current construction phase of our public buildings and characteristics of the status of the fire.The paper makes up researches for fire danger sources of construction phase,describes the construction of public buildings fire tree and carries out qualitative analysis,obtains the all basic events importance and ambiguity degree,and draw the importance sort of all event.4.Set up the framework of fire contingency plans to public building construction site.For fire hazards sources of the construction phase,the paper puts up that the fire safety measures of construction phase should research to technical,organizational measures,the system management.By studing fire emergency plans,the paper sets up the framework of fire contingency plans,researches the basic tasks of emergency plans, organization construction and function partition,response to fire steps and management plans.5.The fire safety reliability analysis and risk assessment of public building use phase.The paper makes analysises and researches to degree of pre-loss in use and maintenance phase based on structural reliability theories,analyzes public building impact of fire casualties and their mutual relations.According to the basic Petri Net Theory and the modeling method,the paper constructs the fire risk assessment Petri model in use phase.At the same time,the paper makes study to fire risk assessment method with fire subjective factors,puts up a simple,fast qualitative fire risk assessment method to non-accidental fire hazards.6.The legal system of fire risk,fire insurance system,supervisors of fire risk have been studiedFirst,the paper analyzes the fire hazards legal system and its characteristics of the United Kingdom,the United States and Japan,and discuses the fire management and legal system of our country.At the same time,the paper makes comparison study to the United Kingdom,the United States,and Japan's current fire insurance systems,and analyzes the status of fire insurance,fire insurance in China,explores the development trend of the systems,presents the development of China's system of fire insurance six ways.Finally,the paper analyzes and discuses the main fire risk management game relationship between the fire departments and insurance companies.
