Abstract

This study analyzes the efficient floor layout plan of classrooms for securing evacuation stability in school in case of fire by using the Pathfinder simulation program. Efficient evacuation methods and safety were evaluated by analyzing REST (Required Safe Egress Time) according to the allocation of personnel by floor targeting a high school 5-story building equipped with a ramp and stairs. The current status of personnel assignments exceeded the Required Safe Egress Time(RSET), resulting in a problem with evacuation safety. When students were placed on the 3rd, 4th, and 5th floors, the result was that the time exceeded RSET the most. When students were placed on the 1st, 2nd, and 3rd floors, the result was that they completed evacuation in the shortest time, less than RSET. In the current state, when evacuation was guided by designating an evacuation exit depending on the location, the result of shortening RSET was obtained. As a result, it is effective to put the students on the lower floors when placing students in high-rise school buildings in terms of evacuation safety, and in the preliminary training, it is required to designate evacuation exits so that they can use the nearest exit for each location in case of a fire. As a future research project, additional research is needed on the RSET when a fire occurs in a specific location according to whether the automatic fire door at that location is opened or closed.

이 연구는 패스파인더 시뮬레이션 프로그램을 활용하여 학교의 피난 안전성 확보를 위한 효율적인 학급 층별 배치 방안 분석을 목적으로 한다. 경사로와 계단이 함께 설치된 고등학교 5층 건물을 대상으로 층별 인원배치에 따른 REST (Required Safe Egress Time, 피난소요시간)을 분석하여 효율적인 피난 방법과 안전성을 평가하였다. 현재 상태의 인원배치는 기준 RSET을 초과함으로써 피난안전성에 문제가 있다는 결과를 얻었다. 학생들을 3층, 4층, 5층에 배치했을 때 기준 RSET보다 가장 많은 시간을 초과하는 결과를 얻었다. 학생들을 1층, 2층, 3층에 배치했을 때 기준 RSET보다 가장 짧게 피난을 완료하는 결과를 얻었다. 현재의 상태에서 위치별로 피난출구를 지정하여 피난을 유도했을 때 기준 RSET을 단축시키는 결과를 얻었다. 결과적으로 고층 학교 건물에 학생들을 배치할 때는 저층부터 배치하는 것이 피난안전성 측면에서 효과적이며, 화재 시 위치별로 가까운 출구를 활용하여 피난할 수 있도록 피난출구를 지정한 사전 훈련이 필요하다. 향후 연구과제로 특정 위치에 화재가 발생했을 때 해당 위치의 자동방화셔터의 개폐여부에 따른 RSET에 대한 추가적인 연구가 필요하다.
