1、防火平安矩阵外文文献及翻译 THE FIRE SAFETY DESIGN OF APARTMENT BUILDINGS13 FIRE SAFETY MATRIXThe objective of this fire safety matrix is to provide a guide for the fire engineering design of apartment buildings. The matrix is only intended for guidance and an appropriately qualified fire safety engineer should v
2、erify the final designThe three main fire scenarios that should be considered in the design of apartment buildings are: a smouldering fire in an apartment, a flaming fire in an apartment and a fire in common spaces ie stairs and corridorsIrrespective of the building and occupant characteristics, som
3、e minimal fire safety measures should be implemented in all apartments. The following is a list of essential fire safety measures that should be provided in all apartment buildings:Smoke detectorsHeating, ventilation and air conditioning HVAC system to shut down on fire alarmA 30-minute minimum fire

Other occupants remain in their rooms, waiting for fire brigade assistance and advice, and carry out protect-in-place activities?Staged evacuation ? occupants in the room of fire origin and on the fire floor evacuate first. The remaining occupants are directed to evacuate automat

Occupants on levels below the fire floor are evacuated last.Fire brigade intervention can alter the sequence of evacuat

8、sists of numerous variables and interdependencies. These variables have to be considered concurrently to provide the most effective design.The selection of fire safety measures in many cases results in a trade-off between various alternatives. For example, sprinkler protection can permit a reduction
9、 in fire resistance rating required for buildings and may allow extended travel distances. These trade-offs and interrelationships between fire safety measures need to be considered to obtain the most efficient and effective fire safety design.Table 14 lists some of the fire safety measures that sho
10、uld be considered for apartment buildings. The variables presented are not a comprehensive list, and other fire safety measures may be more appropriate for more complex designs.Table 14 ? Matrix variables13.4 Buildings greater than 25mThe fire safety matrix for buildings greater than 25m high is pre
11、sented in Table 15. The matrix provides the recommended fire safety measures for apartment buildings with respect to sprinkler protection and the emergency strategy. The matrix provides a simple method of determining some of the minimum fire safety requirements of an apartment building. It can also
12、be used to evaluate which type of emergency strategy would be most effective, or when sprinklers would be beneficial given certain building conditions. The justification of the recommended fire safety measures is pvided in Section 14.1.Table 15 ? Fire safety matrix: buildings greater than 25mthe abo

As the building height increases, the number of fire protection measures also increases to provide additional levels of protection and maintain the level of safety for the occupants.Table 16 summarises the occupan

This key remains the same for all cases presented.Table 16 ? Levels of fire safety buildings greater than 25mTable 17 ? Cel
