고시원 피난계단 폭의 변화에 따른 피난 안전성 평가

Abstract

This study focused on the fact that multiple living facilities (gosiwons) can have more rooms on the same site by taking advantage of the fact that the parking area is smaller than the parking lot area (as stipulated by the parking lot law) and multifamily housing, and further evaluated the performance-oriented design of a gosiwon's firefighting facilities. By creating a scenario using standard guidelines (2021), fire and evacuation simulation programs were used to calculate the evacuation time according to life safety standards, with the number of people who could evacuate being calculated according to the change in the width of the escape stairs at the Gosiwon facility. As a result of this analysis, the group that underwent evacuation training and Scenario 6, in which the width of the evacuation stairs was expanded to 2m, showed the shortest evacuation time of 296.3 seconds. As a result of conducting an evacuation simulation for the same building without changing the width of the stairs and fire drills, the evacuation time was shortened by 165.2 seconds from the evacuation time of 461.5 seconds. As a result of this analysis, it is necessary to add the width of the evacuation stairs to the types of safety facilities under the Multi-Use Business Act so as to improve the evacuation safety of gosiwons. In addition, multi-use establishments with 11 or more floors were added to the fire training and education targets as stipulated in the Fire Prevention Act, allowing training to be conducted together with fire agencies, thereby securing evacuation safety and laying the foundation for the revision of the laws.
