Study on Fire Prevention Performance-Based Design of a Large Underground Banquet Hall

Abstract

There is large fires risk and difficult evacuation in underground buildings, so it is necessary to study the development of fire and evacuation procedure in underground building. In this paper, a large underground banquet hall was chosen as an example, evacuation safety in the hall was analyzed by numerical simulation. First of all, fire model and two fire scenes were set up by using the software Fire Dynamics Simulator. Then the process of fire spread was reappeared by numerical simulation, and evacuation process was simulated by using the software PathFinderTM. By comparison with both result, it was proved that there is safe personnel evacuation in the case of effective fire-fighting facilities. According to the simulation results, reasonable recommendations about fire safety of the large banquet hall was proposed. The research will contribute to fire prevention and architecture design.
