建筑物安全疏散模型与计算方法

With contemporary science and technology passing everyday, creating the possibility of an unprecedented to the building, and the safety of buildings are also increasingly prominent, and the lack of security can not be said that the building is a qualified building, in real life due to ignorance of the safety of the design and construction led to frequent disasters. In this paper, according to a building evacuation routes on the corridor, staircase and the entrance of the former rooms, staircases, etc. above the width of the staircase, rooms of different sizes, such as the former through the establishment of model calculation, to ensure that people can fire a certain period of time to evacuate to security zone. Safe evacuation of the calculation is based on the assumption of a layer of fire, the forecast of the layer were all evacuated to the lower deck and check the safety of the evacuation chain. Generally for the units on each floor to check, but can also be based on building size, shape, nature of the use of only a sub-checking the safety of their evacuation or the evacuation of several at the same time, or full building evacuation safety .
