  • 지하연계 복합건축물의 건립이 급증함에 따라 건축물의 피난 성능이 중요시되고 있으며 복잡 다양해진 피난유도에 대한 피난시설 배치와 RSET(Required Safe Egress Time)이 필수적으로 관련 지침에 명시되고 있다. 그러나 RSET에 대한 신뢰성 검증 및 용도별 수용인원 산정 방법이 주관적인 관점에 의해 제시되고 있으며 이런 검증 자료의 검토기준이 정량적이지 않아 안전성 확보가 이뤄지지 않고 있는 것이 현실이다. 따라서 본 연구에서는 지하연계 복합건축물의 피난 안전성을 확보하는데 가장 적합한 검증을 위해 방재 선진국의 ASET 기준을 심층적으로 분석하여 지하연계 건축물 등에서 국내 실정에 맞게 적용할 수 있는 최적화된 ASET을 도출하였다. 이러한 ASET의 신뢰성을 검증할 수 있도록 피난안전구역 및 준하는 구역의 현실 가능성을 분석하고 국내 외에서 상용화되고 있는 피난시뮬레이션 소프트웨어를 통해 건축물의 용도에 따른 수용인원 산정기준의 현실적 방안과 피난경로 설정의 Logic을 감안하여 피난의 안전 및 최단시간 가능성을 고려하였다. 따라서 지하연계복합 건축물에서 요구하는 피난성능과 수용인원의 최적화된 RSET을 정량적으로 도출함에 따라 피난 안전성에 대한 검증 프로세스를 제시하였다.

  • Escape distance and escape barrier are critical elements for the quantitative evaluation of escape safety. Through theoretical demonstration and modeling in precedent studies, they have been analyzed for their generality and applicability. To make more practical evaluation method, we should quantitatively analyze the influence of each barrier and escape condition on escape safety considering various barriers in escaping routes. In this study, to develop more accurate and applicable escape analysis model, we have focused on three research methods as below: First, we derived quantified function to predict various escape barriers in escaping routes by theoretical analyses of the escape barriers and conditions. Second, we substituted the derived quantified function for an evaluation tool of escape safety suggested by precedent studies. Third, we examined applicability and feasibility of the developed method by modeling with the consideration of the escape conditions and barriers.

  • This study is for increasing evacuation safety by analyzing RSET(the required safe escape time) through the arrangement of personnel by floor and by room while evacuating in a Girls' High School Dormitory. For this study, PAPS(Physical Activity Promotion System) results that have not been studied so far were analyzed and reflected in evacuation simulations on the premise that individual student's physical strength can affect evacuation. Based on the PAPS results, four scenarios were applied. In addition, evacuation simulation using the pathfinder program was conducted in two situations: the evacuation route was assigned or not. Scenario 4 was the fastest at 168.5 seconds of RSET in assigning evacuation routes among scenarios. As a result of this study, the arrangement of students focusing on improving their academic ability and student life guidance excluding student physical strength has problem. In order to solve this problem, it is effective to place C group students(low grade on PAPS) on low floors and A group students(high grade on PAPS) on high floors and to assign evacuation routes in each room. In the future, the following ways need to be more studied. A study on how to increase evacuation safety through practical evacuation training, the way of assessing evacuation safety reflecting the lifestyle and physical strength of girls, the evacuation route assignment according to the fire occurrence point, and the method to secure evacuation routes in the event of a fire near stairs or entrances should be conducted.

  • University dormitory has some weaknesses against disaster such as fire because of high population density and strict control of access in night time. The purpose of this study is suggestion of a guide of effective floor plan for improvement of evacuation safety. Plans for preventing disasters are studied and evacuation safeties are analysed using network model analysis method according to plan types. The weakness of disaster prevention is quantified, and effectiveness of bidirectional evacuation is confirmed. The circuit type floor plan shows best evacuation characteristics and this result is anticipated to be adopted to design process of new dormitories and will contribute to improvement of evacuation safety.

  • 불특정다수의 사람들이 이용하는 숙박계시설이며, 자립피난이 곤란한 피난약자에 해당하는 환자 및 노약자, 임산부, 어린이가 대다수 이용하는 병원은 피난안전상 매우 불리한 용도의 건축물이라 할 수 있다. 따라서 본 연구에서는 실재병원의 건립 당시 평면계획과 실재 사용 중 평면을 조사하고, 이를 대상으로 본 연구의 선행연구에서 발표된 피난안전성의 평가법에 적용하여, 병원 평면의 변화에 따른 피난안전성의 변화를 정량적으로 나타내는 것으로, 불가피한 평면의 변경 시에 참고자료로 활용 될 수 있는 근거를 제시 하고자 한다.

  • 선박화재는 육상과 달리 숙련된 인원과 다양한 장비에 의한 소화활동이 곤란하며 거의 자체적인 진화작업을 수행해야하므로 소화가 쉽지 않다. 화재는 일반적으로 화염에 의한 인명사고 보다 매연에 의한 질식사의 확률이 높으므로 인명사고를 방지하기 위해서는 신속한 초기 진화가 가장 중요하다. 하지만 여러 가지 이유로 부득이 소화가 지연되거나 불가능할 경우에는 화재 구역으로부터 신속한 탈출만이 인명사고를 방지할 수 있다. 이 연구에서는 CFD기법을 이용한 시뮬레이션을 통하여 선박화재시 탈출에 지장이 되는 매연농도를 측정하고 피난시간과 비교하여 적절한 피난이 가능한지에 대한 안전성을 검토하고자 한다.

  • In this study, using the FDS as the fire simulation and evacuation simulations of the Pathfinder, set the main control room of the building to the fire point fire safety assessment studies were carried out. At first the quantitative result such as distribution of visibility as time passing, distribution of temperature, distribution of CO density produced results using fire-simulation and evacuation-simulation was carried out based on the result that produced the final safety evaluation result as being calculated of evacuation time. As the risk increased with the distribution of visibility at the result of fire-simulation, evacuation-simulation was carried out using the result. Finally the result was made 127.9 sec that everyone could evacuate. The numerical results are analyzed in case of the places in the building required safe egress time for safety a as the analysis to be no more than available safe egress time was analyzed to be secured. The results of this safety evaluation represent that more smooth evacuation safety performance can be secured by linking the event of fire firefighting equipment as a result of simulating the worst conditions.

  • In this study, fire and egress simulation was conducted for the egress safety evaluation of the nursing hospitals. A fire simulation was performed with or without the smoke exhaust system using the FDS, and the available safe egress time (ASET) of the nursing hospitals was calculated. In addition, an egress simulation considering the characteristics of occupants and egress delay time was performed using Pathfinder, and the required safe egress time (RSET) was calculated. By comparing the ASET and RSET, the egress safety of the nursing hospital with or without a smoke exhaust system was evaluated according to the number of egress guides and the egress delay time. The simulation results show that the number of casualties increased as the egress delay time increased, and the required safe egress time decreased as the number of egress guides increased. In addition, it was found that if a smoke exhaust system with the capacity specified in the KFPA is secured, the available safe egress time can be greatly increased and the number of casualties can be greatly reduced.

  • 최근 대형화된 재난사고가 빈번히 발생하고 있으며 이에 따른 건축물의 피난설계가 중요시 되고 있지만 일반인에 비해 재해 시 피난이 곤란한 재해약자가 이용하는 시설에서의 성능설계나 피난계획은 미흡한 실정이다. 따라서 본 연구에서는 국내 장애인 복지시설을 대상으로 피난안전성평가를 실시하여 그 문제점을 도출하였으며 그 결과 장애인시설의 피난안전을 위해서는 피난개시시간, 엘리베이터 피난, 내장재, 발코니 유무, 출구 폭 등의 문제점에 관한 대책이 시급하며 또한 성능기반 피난안전설계 의무화가 우선시 되어야 할것으로 판단되었다.
