| Summary: | The construction of high-rise and multi-functional commercial buildings has emerged as a global trend, but it also introduces significant fire hazards. Consequently, there is a pressing need to examine the fire development trends in super high-rise commercial buildings and establish logical evacuation strategies. This study utilizes the Pyrosim program to simulate a typical fire scenario at the Yangtze River International Conference Center, allowing for the acquisition of essential fire parameters and available evacuation time. Subsequently, based on the complex functional zones and personnel distribution within the building, appropriate evacuation plans are devised and simulated using the Pathfinder software. The results reveal that by effectively utilizing stairs, elevators, and refuge floors in accordance with personnel distribution, evacuation efficiency can be substantially enhanced. Furthermore, the required evacuation time during nighttime fires is merely 36.6%–55.3% compared to unorganized evacuation. The findings of this study offer valuable theoretical guidance for the evacuation of super high-rise commercial buildings, holding immense significance in minimizing fire-related casualties within such structures.
