Simulation study on pedestrian evacuation during fire in high-altitude sealed buildings
This study investigates the impact of transition compartments and auxiliary evacuation exits on fire evacuation in high-altitude airtight pressurized buildings,considering the building's pressure relief time and evacuation mode.The design requirements for safety exits in high-altitude enclosed pressurized buildings are proposed.The results indicate that for high-altitude sealed buildings with an area of 200~500 square meters,the emergency pressure relief time should not exceed 60 seconds.To ensure evacuation safety under fire conditions,at least two transition cabins with a door width of no less than 1.0 m should be set up as evacuation exits.In cases where this requirement cannot be met,at least one additional emergency escape door or window directly connecting to the outside should be added along the main evacuation route as auxiliary evacuation exits.These research results provide crucial insights for enhancing safety design in high-altitude sealed buildings.
