Under the Korean Enforcement Decree of the Building Act, all high story apartment houses more than 5 stories high are mandated to install a fire evacuation system to ensure safe evacuation from fire accidents and providing quick and easy bidirectional escape route when main entrance is blocked by flame or toxic smoke. However, the current fire evacuation system shows a lack of understanding from residents and thus is widely ignored for having insufficient safety functions, especially vis-à-vis fire emergencies. Studies have found that an alternative evacuation method, the escapable fire evacuation system, has been analyzed for safety evaluation compared with the conventional passive fire escape system and can bring efficient and safer solutions, providing high rise residents escape from fire accidents. Evaluation for safety evacuation has been performed by the Fire Dynamics Simulation and applying Pathfinder simulation. This resulted in providing appropriate escape routes within the safety escape time and allowed for people in high rise building fires to get to safety.

The purpose of this study is to propose measures to increase evacuation safety by calculating the habitable time using a fire and evacuation simulation program for the Room-escape cafe currently in operation, and comparing and analyzing it with the evacuation required time. Assuming a fire due to overheating of electric heaters in use in front of the warehouse, the habitable time was calculated through fire simulation, and the occupant's evacuation time calculated through evacuation simulation according installation of safety facilities, etc. was compared and analyzed with the habitable time. In the case of escape room cafes with safety facilities installed, evacuation safety was satisfied, but in escape room cafes without safety facilities, the evacuation safety was not secure. As a result of analyzing evacuation safety for each scenario based on the ASET analyzed in the fire simulation, it was found that in scenario 1, evacuation safety was secured and everyone successfully evacuated, while in scenario 2, no one succeeded in evacuation. These results can be said to confirm that the installation of safety facilities is very important in business establishments such as escape room cafes, which become enclosed structures when games are started.

본 연구는 청주소재 OO 고교 교직원 휴게실에서 화재상황을 가정하여 FDS와 CFAST 화재모델을 이용하여 화재특성을 분석하였으며, 전교생을 대상으로 실제피난훈련을 실시하고, 피난프로그램 Simulex를 수행한 자료와 비교하여 피난안전성을 평가하였다. 그 결과, 실제피난훈련은 8%가 피난에 실패하였고 Simulex에서는 40%가 피난에 실패한 것으로 평가되었다. Simulex는 피난경로, 피난집결지 둥 실제피난훈련의 특성을 반영하지 못한 것으로 나타났다.

A guideline to complement safety problem of escape code at the fire controlling design stage was shown by comparing & analysing developed fire controlling countries such as US, UK, Japan, and etc. and appropriateness of improving legislations for building standard of escape code was examined by comparing & analysing escaping time with escape code simulation(SIMULEX, EXDOUS) as the guideline.

The objective of this study is to verify the safety in case of fire and change of residential environment for different wall construction approaches in a stairways apartment house. In order to confirm that case_1, which is current case that most of wall is opened and the case 2, which upper part of wall is limitedly opened are compared and analyzed based on simulations of fire, escape and natural ventilation performance. The analysis reveals that possible escape time for case 1 was more than 600 seconds and for case 2 was 195 seconds. Since the escape times for both cases were over 128 seconds, it would be reasonable to assume that every resident would escape. The simulation results on natural ventilation performance shows the air change per hour of case 1 and case 2 were .19n/h and .16n/h and there was 1.2 times difference. However, the difference was too insignificant and it could be seen as that different approaches on wall construction would not significantly influence on natural ventilation performance.

방재설계를 하는데 있어서 피난의 주체인 재실자가 화재시 신속하고 안전하게 피난 가능 하도록 피난방법의 최적으로 정립하는 것이 핵심적 사항이다. 건설 기술의 발전으로 많은 초고층 건축물이 세워지고, 초고층 건축물은 다양한 위험을 내포하고 있으며 재해의 정도를 증대시키고 있다. 초고층 건축물의 기본 설계 단계에서, 화재시 재실자가 피난 계단과 엘리베이터를 동시에 시용하여 피난하는 것을 고려 할 수 있으나, 이러한 피난 계단과 엘리베이터를 동시에 이용안 대피 성능 평가는 적립되어 있지 않다. 본 연구에서는 Virtools를 이용한 VR 기법을 사용하여 화재시 재실자가 비상 엘리베이터 및 피난계단을 동시에 이용하여 피난 할 경우에 대한 대피성능평가를 시뮬레이션을 통하여 분석하였다.

When a fire takes place, the escape tunnel which could prevent passengers and the crew from disasters would be most important facility among railway tunnel facilities for prevention of disaster. A shorter space between the escape tunnels is much better for safety because of short escape time. The establishment of short space escape tunnels(driftways) in the single track parallel tunnel is much easier. The establishment of long space escape tunnels(inclined shafts, vertical shafts) in the double track is much more advantageous economically. We, therefore, compared the movement time of smog originated from fire with the escape time of the crew and passengers for setting up the best space between the escape tunnels in the double track tunnel. We could calculate the best space between the escape tunnels in the double track tunnel properly by computer simulation.

It has been recognized that the escape facility planning is very important for effective evacuation of accupants on fire event. The ultimate goal of the escape facility planning is to evacuate occupants rapidly from building fires to the safe areas. In fire event, occupants usually gather, utilize and finally act upon information about state transient of building fire system, which is consisted of components of fire, building and accupant during the ralatively short period of the fire event. That is, occupants' egress behavior is largely dependent upon building fire system. Therefore, comprehensive study for the relationship between building fire system and occupants' egress behavior is needed. This study aims to suggest the pre -occupancy evaluation method of the life safety performance for the architectural design based on prediction of occupants' egress behavior during building fires with computer simulation.

When caught in a fire inside a building or a tunnel the generated smoke is the main cause of the bad visibility, which makes difficult for a person to find escape route. Therefore it is required to visualize the simulated results of smoke realistically from a viewpoint of a person caught in a fire. In the present study, demonstrated is a CFD post-processor which can visualize the objects through smoke from the results of CFD fire simulation.
