Research on fire evolution mechanism of terminal buildings coupled with fire fighting facilities

Abstract

Abstract:

Airport terminal is a large public building, it can easily cause smoke accumulation and make evacuation difficult once a fire occurs. Traditional fire fighting facilities are difficult to meet the fire fighting needs of such buildings.

In this paper, the evolution mechanism of coupled fire facilities is studied. Firstly, the building information modeling (BIM) of terminal hall is established, and the fire simulation of terminal in different scenarios is carried out through fire dynamics simulator (FDS). Then the data of sprinkler operation, smoke layer height, visibility and heat release rate in different regions and different scenarios are obtained. The fire evolution mechanism is analyzed according to the changing process. The results show that there is a significant difference in the fire evolution mechanism between the coupled fire fighting facilities and the non-start-up fire fighting facilities for the special public building such as airport terminal. At the same time, the simulation results can provide ideas for the optimization of fire fighting design and the formulation of emergency evacuation plan of airport terminal.
