Study On Safety Evacuation During Fire In Fuxin Xinglong

Construction safety plays a more and more important role in the modernization construction and development,building fire safety is the priority among priorities in building security,fire performance of the building is the understanding of buildings is a part of the security necessary.In order to ensure whether the personnel inside the building can be reached in the safe evacuation of dangerous state buildings when building fire,the evacuation of fire simulation and the personnel in Fuxin City Xinglong building,analysis of different scenarios when a fire occurs,whether in the mall to evacuate all personnel to safety in a certain period of time,so as to prosperous family of fire safety measures in construction can provide a strong basis for the.According to the actual structure of the Xinglong,predict the possible occurrence of fire will cause serious consequences for the building site,located in the middle of the atrium and indoor Street corridor at different location of fire source,building fire simulation after the disaster in the fire spread by using Pyrosim software.The qualitative and quantitative analysis of the change of temperature,the fire spread and smoke concentration in flue gas of combustion and heat release rate change;set in different locations of the building's temperature monitoring points,heat flow monitoring,smoke height detection line to determine the changes of physical parameters in a fire,the fire in the physical parameters changing with time.Through the description of the physical parameters in the fire,the fire danger time of buildings under different scenes is obtained.At the same time,the Pathfinder software is used to simulate the movement of the people in the building,and the safe evacuation time is obtained when the fire occurs.With the building fire risk time to compare,can be obtained under different fire scenes,whether to escape all the personnel in building fire risk in time,to determine the safety evacuation of each scene personnel.The evacuation process of buildings is simulated by computer,and the theoretical evacuation time is calculated.Compare the time with the escape time of fire simulation in the shopping mall,and get the validity and practicability of Pathfinder software,which can be used in the actual situation.
