The Reserch On Fire Risk Assessmen Of One Expo Center

In the recent years, large numbers of buildings and public entertainment places have been build in city, which are complex in function and large in scale. At another time, it has the reasons in dense settlement, dense buildings and difficulty in scatter. They will bring about a great damage of lives and property in fire. And it's an evil influence on society. Because the current design regulations do not admit of any solution of these constructions, it is possibly through the use of fire risk assessment. It can be objective and accurate understand in danger of fire, which can offer the solution to prevent fire risks, reduce them and put out a fire to safe life and property.Based on the research of the related field in fire risk assessment, the dissertation estimates the design of the Expo Center . Firstly, by analyzing the features of the Expo Center's location, structure, function , visitor, fire extinguishing system, it discovers the problems of design , and establishes the scheme of the fire risk assessment. The evacuation simulation software Pathfinders is used for the evacuation scenario analysis, the safe evacuation of staff time calculated in all kinds of scenarios is for judging the effectiveness of atrium smoke extraction system and providing a reference; hydraulic model is used to calculate the evacuation of staff time, personnel in the process of the evacuation is conducted by uncertainty analysis. we analyze the uncertainty of the spread of fire, use of the fire development of analytical tools to set the corresponding fire scenario and simulating motion law of flue gas, use the fire dynamics simulation software FDS which is commonly used in fire safety engineering to simulate the fire smoke movement which the fire scenario has been identified, and to determine whether the fire separation designed could control a fire in the set area ; in the end, establish the reasonable solution and advisement.In the dissertation, we assess the design of the Expo Center. But it must be bond with routine work for favorable effect of the fire facility.
