In this study, we investigated whether the evacuation time according to the exit installation standards specified in the building code during a food factory fire is compatible with the evacuation time based on the performance-based design specified by the fire department, in order to determine if evacuation safety is ensured. We used the Pathfinder program to confirm the evacuation time, and experimented with three scenarios for exit installation standards towards the outside of the building: 60m, 80m, and 100m. The target building in the experiment corresponded to the building code's exit installation standard of 100m from each dwelling. The experimental results showed tt in the cases of 80m and 100m, ASET exceeded RSET, indicating tt evacuation safety was not ensured, while in the case of 60m, evacuation safety was maintained. Through this study, it was confirmed tt even when the exit installation standards towards the outside of the building are met, evacuation safety may not be guaranteed.

In this study, compare and analyze for high-rise evacuation safety design criteria improvement about internal high-rise building egress safety rule. To the result, high-rise evacuation safety design criteria improvement data can be summarized as follows. First, should compute the evacuation capacity about the number of persons and when more than 2 exits are requested, over 50% of evacuation capacity must be satisfied even approaching to 1 exit is unable. Second, 2 ways of evacuation can be made smoothly by the stair or exit separation-distance standard regulation. Third, regulate the length limitation of dead-end corridor or passageway and it should give grades in limitation of whether the spring-cooler has been installed. Fourth, must secure the evacuation way and do the evacuee guidance when it's safety area and elevator or stair. Also needs to provide extra safety area to secure horizontal direction Escape Safety except fire escaping floor.

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.

최근 건축물은 초고층화 대형화 지하심층화 되어가고 있다. 한편, 이러한 건축물은 화재시 기존의 건축물 보다 피난안전성의 문제가 대두된다. 이에 따라 국내외에서는 성능적 피난안전계획을 목적으로 PBD를 시행하고 있다. 하지만 국내의 경우 국외에 비하여 그 방법론이 부족하고, 건축물의 피난용량이 부족한 시점에 놓여있다. 이러한 배경을 통하여 본 연구는 재실자 피난행동분석 중 피난계산에 중요한 요인인 출구유동계수를 조사하고, 기존의 국내외 문헌과 비교를 실시하였다. 이에 따라 종합표준치 1.88인/ms를 도출하였으며, 또한 실태조사의 한계성을 파악하고, 이를 통한 조사기법에 대한 프로세스를 제안하였다.

Korea faces The 2014 Incheon Asian Games and 2018 Pyungchang Winter Olympics. It is imperative to hold a safe event for the economic benefits, enhancing Korea's image, social integration, national harmony and unity in order to be evaluated as a successful international event. Furthermore, since the international event tends to draw many spectators, the host country must be ready to accommodate a large number of injured people in the event of an accident or terror attack. As stadiums for international events are where a large number of spectators gather in, a large refuge is essential, when dangerous situations happen. In this study, evacuation simulation was conducted using three scenarios in order to predict escape behaviors of spectators during the large escape by destruction of safety systems of stadiums and assess escape safety. As the result, the following results and proposals were extracted. Firstly, it is considered that dangerous situations during the security of stadiums should be predicted in advance and concrete plans for a large refuge of spectators have to be established to minimize damage. Secondly, it was found that the reduction in evacuation exits has an important impact on evacuation in an emergency situation. It implies that securing escape exits are quite important. Thirdly, there were areas where spectators stayed, due to blocked escape exits, while they were dispersed and concentrated at once. It demonstrates that security plans considering properties of facilities are required to solve these problems.

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.

모든 공동주택에 적용되고 있는 기존의 피난시설은 고층부분에서 사용의 제한, 세대 간 보안 및 사용자의 제약 등으로 실제 현장에 적용하여 사용하는 되는 많은 문제점을 내포하고 있다. 또한, 이와 관련하여 공동주택의 용도 특성상 조기 피난이 이루어지지 못하는 경우가 빈번하여 화재 때문에 세대 내 출구가 폐쇄되고 재해약자가 사용하는데 어려우며, 화염과 복사열로부터 안전을 해결하기에는 현재 공동주택에서 보편적으로 설치되어있는 완강기로 이러한 문제를 해결하기에는 매우 미흡한 실정이다. 이에 본 연구에서는 이러한 문제점을 해결할 피난방법이 적용된 피난시설을 제안하고자 한다. "피난대피시설"은 공동주택 발코니 또는 외벽에 콤팩트(compact)하게 접혀 있다가 화재 시 수동 또는 감지기와 연동해 쉽게 작동되어 대피공간 용도와 유사시 자력으로 피난층까지 피난할 수 있는 구조이다. 또한, 화재실과 접하는 부분은 $1,200^{\circ}C$의 복사열을 차단할 수 있는 단열소재로 구성되며 1차적으로는 화재 장소에서 외부 공간으로 일탈한 후에 2차적으로 아래층으로 사다리를 이용하여 피난할 수 있게 되어 있다. 본 연구개발의 주안점은 화재 시화염과 복사열로부터 공간 일탈을 하여 재실자를 보호할 수 있는 대피공간의 개념과 피난시설에서 피난층으로 피난할 수 있는 적극적인 피난방법을 접목한 것이 피난시설 개발의 핵심이다.

It is important to conduct various analyzes to evacuate occupants in advance, because the disaster can cause serious injury. Therefore, it is necessary to analyze all the predictable scenarios that may occur. In this study, we propose a method to analyze the evacuation of indoor disaster using activity - based transport model MATSim. We have developed the university building as target area and simulated about 5,000 occupants. The analysis scenarios are set as basic evacuation conditions, exit closures and emergency stair closures. As a result of analysis of each scenario, the evacuation time was analyzed to be about 5:40(340s) in the base scenario, increased by 15% in the scenario 2 and increased by 23% in scenario 3. As a result of this study, we suggest that it is important to manage illegal obstacles of emergency stairs for rapid evacuation. Therefore, this study can contribute to the effective disaster prevention strategy of the building.

Emergency response of fire prevention manager has an effect on decisive emergency exit behavior of customer who is not accustomed to emergency response in a large-scale shopping department on fire. Especially enclosed stairways in a large scale store are usually located in back space where is impossible for customer to access. Therefore, speedy emergency exit inducement by fire prevention manager is needed for the customer's safe egress. The object of study is to analyse the factors affecting egress behavior and emergency response of fire prevention manager in respect of fire prevention management.
