Abstract: To clarify the evacuation bottleneck of air-rail intermodal hub stations and improve the efficiency of personnel evacuation, the smoke spread process and the visibility and temperature changes in the case of fire in an air-rail intermodal hub station in Zhengzhou, Henan, China, were simulated via PyroSim simulation software based on performance-based fire protection design technology. The available safe escape time was obtained, the whole process of safe personnel evacuation was simulated, the bottleneck position in the process of evacuation was revealed, and the time required for safe crowd evacuation in the fire environment was determined. Results show that with a smoke exhaust system, smoke spreads to both sides of the hub station in 270 s, the visibility on both sides is affected, and the safe evacuation conditions fail. When the smoke exhaust system does not function, the available safe escape time is 497 s, and the required safe escape time is 370.5 s. The obtained conclusions provide a decision reference for performance-based fire protection design of air-rail intermodal hub stations. [ABSTRACT FROM AUTHOR]
