Comparative Analysis of Evacuation Safety in Nursing Hospital under Korean and Chinese Standards

Abstract

This study presents a comparative analysis of Required Safe Egress Time in a nursing hospital setting, utilizing

stochastic occupant models derived from both Chinese (GB/T 10000-2023) and Korean (Performance-Based

Design Evaluation Guidelines) anthropometric standards. While previous research often assumes standardized

occupant profiles, this paper investigates how inherent differences in population body dimensions and

movement speeds between the two countries can lead to divergent safety assessments. Using Pathfinder

agent-based simulation, we evaluated four evacuation scenarios, including the strategic addition of external

ramps on various floors. The results reveal that evacuation times based on Korean anthropometric parameters

are consistently and significantly shorter than those based on Chinese parameters across all scenarios, with the

maximum discrepancy reaching 23.8% in the most optimized ramp configuration. Our findings underscore that

incorporating nation-specific occupant data is crucial for performance-based design, particularly in facilities

for the elderly. Furthermore, the study confirms that adding external ramps is a highly effective strategy for

enhancing evacuation safety, regardless of the standard applied. This cross-national comparison provides

valuable insights for internationalizing building safety codes and optimizing nursing hospital design for

specific demographic groups.
