Purpose: Compared to general fires of the same size, underground parking lot fires are more likely to cause human and property damage and are not easy for firefighters to extinguish fire and save lives. This study attempted to find out how to secure the evacuation safety of parking lot users based on changes in the evacuation simulation behavior mode applied to evaluate the evacuation safety of the object. Method: Simulation for each CASE was performed using the Pathfinder program. Result: it was found that the higher the reference value, the higher the evacuation time, and Behavior showed an increase in time in SFPE mode rather than Steering mode. Priority was able to confirm an increase in time in priority designation rather than non-priority designation. Conclusion: The Required Safe Egress Time (RSET) for evaluating the evacuation safety of underground parking lots and the building evacuation design to ensure evacuation safety should be evaluated and reflected separately from Simulation's Behaviour Mode and Priority.
연구목적: 지하 주차장 화재는 동일 규모의 일반화재에 비하여 인명 및 재산피해의 우려가 크고 소방관의 소화활동 및 인명구조가 용이하지 않는 특성이 있다. 본 연구에서는 대상물의 피난안전성 평가를 위해 적용되는 피난 Simulation 행동모드의 변화를 기반으로 주차장 이용자의 피난안전성 확보방안에 대하여 알아보고자 하였다. 연구방법: Pathfinder 프로그램을 사용하여 CASE 별로 Simulation을 수행하였다. 연구결과: 기준값이 높아질수록 피난시간이 증가되는 것을 알 수 있었으며, Behavior는 Steering Mode 보다는 SFPE Mode에서 시간증가를 나타냈다. Priority는 무순위 지정보다는 우선순위 지정에서 시간증가를 확인할 수 있었다. 결론: 지하주차장의 피난안전성 평가을 위한 피난소요시간(RSET)과 피난안전성 확보의 건축물 피난설계는 Simulation의 Behavior Mode와 Priority을 구분하여 평가·반영되어야 한다.
