The High-rise Building Fire Evacuation Study

China's vast population, the per capita area is limited, in order to save land resources in recent years, high-rise buildings has become a major development in China's buildings. But the high-rise building after the fire occurred, the casualties tend to be more serious reason is that high-rise buildings, the vertical height is too high when the fire broke out, the fire spread too fast, which greatly increased the difficulty of putting out the fire rescue. On the one hand, China in recent years the development trend of China's high-rise buildings quickly, and facilities management system for high-rise building safety and fire to prepare design is still not perfect. On the other hand, at home and abroad on the safe evacuation studies have focused on public places, where more staff, but little research on the safety of persons in high-rise buildings were evacuated. We know that when the fire broke out in different environments, the performance of each person is different. The efficiency of the evacuation is often effective implementation of the evacuation has a direct relationship. To this end, for the case of high-rise building fires occur, how safe evacuation of personnel, focus on the following two aspects were studied and analyzed.For the fire (1) behavioral factors influence people's response from the five aspects of the basic theory of human behavior that staff characteristics,staff characteristics,the structure of the building,the product of fire and safety management and evacuation analysis and reveal the behavior of the basic rules of fire.Through the cluster phenomenon when the fire broke out,come out of the famiy behavior of the staff, and its interpretation from the perspective of psychology and sociology. Qualitative and family behavior in the time of the fire evacuation were discussed,its positive role in household behavior in the evacuation,but to some extent but then evacuated adversely affected.(2)a brief analysis of the advantages of shortcomings exist in the traditional way of evacuation,lift evacuation, analyzes and discusses the use of the elevator in a high-rise building evacuation feasibility.The draw will be in the danger zone took the lead through the elevator evacuation to safe areas is very feasible,and can be some reduction in casualties and evacuation efficiency has been improved. The law of development through the identification and analysis of fire,fire, resulting in smoke spread into the elevator,there is still some time to reach a dangerous state, the fire at this early stage smaller impact on the safety performance of the elevator.Based on these two points recognize the establishment of the evacuation model to dead with the high-rise building fire.And a layer of a high-rise building fire,for example,fire detection time and the pre-movement time is calculated by the methods provided in the Basic Law of the Japanese constructiion.Obtained from the formula to use the stairs to evacuate the time required and the time required to lift evacuation. The data show that:the use of the elevator will be in a dangerous layer of staff early in the fire to evacuate to a safe location, the consumption of time shorter than the stairs, and basically before the fire did not reach a dangerous state will be in a dangerous layer of personnel evacuation is completed.Therefore be seen through the elevator will be in a dangerous layer of staff in the early stages of the fire, the first evacuation to safe areas, enable the evacuation efficiency is effectively improved, reducing the rate of casualties is feasible.
