| Abstract |
Large and complex buildings face serious evacuation challenges due to intricate layouts and occupants’ limited familiarity with the space. To
move beyond the limitations of costly technology-driven approaches, this study applied Pathfinder simulations to the Daegu Shinsegae
Department Store to identify bottlenecks in horizontal evacuation paths. The key contribution lies in proposing and validating a horizontal
distributed evacuation strategy, which reinterprets existing fire compartments as guiding zones for dispersing occupant movement. By utilizing
current infrastructure without requiring new facility investments, the approach demonstrates strong practicality and ease of implementation.
Results show an average evacuation time reduction of 43.36 percent, from 7,460.3 seconds to 4,066.0 seconds, compared to conventional
self-evacuation. This improvement remained consistent, maintaining over 43 percent effectiveness even when occupant density increased to 200
percent of the standard capacity. The findings offer critical groundwork for developing resilient evacuation plans that adapt effectively to
fluctuations in building occupancy, underscoring both academic and practical significance. |
