Through the use and development of underground spaces, subways have become a representative means of transportation in the city center. Due to the extension of subway lines and the increase in the number of subway users, there is a risk that safety for evacuating human lives in case of fire will not be secured. Therefore, this study tried to identify citizens' perceptions of evacuation facilities through questionnaires and find alternatives. An online survey of 115 subway passengers was conducted to learn about citizens' awareness of subway evacuation facilities. As a result of the survey, awareness of evacuation facilities was high in the order of guidance lights, life-saving devices, emergency lights and portable lights, special evacuation stairs, and evacuation stairs. In addition, the majority of the respondents said they were not well aware of evacuation facilities, and people's indifference was the most common cause. As a solution to the lack of awareness, responses to active advertising and promotion, education and experience activities were the highest.

The purpose of this study is to know how visual-field obstruction from fire smoke influences a resident's necessary time to reach fire escape and evacuation movement in a high-rise apartment housing. Generally, fire smoke not only gives visual-field obstruction and breath troubles to residents but interrupts their evacuation behavior. If a fire smoke layer is formed in the core department when evacuee enters at the evacuation staircase until, residents will be made to undergo a range of vision obstacle. In order to set a situation like that, participants wore eye bandage which had been made especially before the experiment. Also as a comparative standard, through no.1442 Japanese construction ministry notices about the building evacuation safety verification method, this study calculated smoke layer's dissent time and evacuation time. Then to compare with the former, the participants without an eye bandage joined a experiment once again. This study has understood how fire smoke effects on one's evacuation delay by analyzing residents' evacuation time to reach the staircase and movement route, however, in this study a toxic gas is not considered because it might threaten participants not to breathe.

There have been the current controversy over effectiveness of the pressurized smoke control systems, which are installed within escape shaft to provide 'smoke-free' access for escaping peoples. Therefore, many effective measures were given in this paper by means of the production of a design guide for various types of escape routes used in domestic buildings. The solutions were established on basis of both an investigating current door closing device application in existing facilities and global standardization for pressurized smoke control system, especially in British Standard. Finally, the design guidance for open door air velocity with introduction to three door protection clauses was presented on the basis of consideration of the safety and economical factor,

The aims of this study are to verify the relationships of evacuee speed and affections to the evacuation time according to the width of corridor and stairs in university education facilities. To achieve these purposes, the present conditions of university education facilities were analyzed, and the evacuation experiments were executed in relation to the width of corridor and stairs. The results of this study are as follows ; (1) The deviations of numbers of residents per stair is very high, and the number and width of stairs, corridors are only depend on the minimum guidelines of building code, not considering the residents' evacuation. (2) The width of corridor and stairs are affects on the evacuation speed and time. The rate of decreasing speed is large in stairs, and also the possibility of danger is increasing depend on the speed and density.

Stack effects occurred in the stairwell, an important evacuation means of the high-rise building, give a big impact on stairwell pressure difference distribution and it could obstruct evacuation from the building, so should be controlled within proper range. Computer simulation was conducted with CONTAMW2.4 to find the solution of stack effects of the high-rise building. It was able to solve the imbalance pressure difference with a pressurization and a depressurization supplied by fans on higher and lower parts of the stairwell.

비상시 엘리베이터의 피난 활용은 피난층과 함께 초고층 및 복합연계건축물의 새로운 피난 수단으로 인식되며 현재 많은 연구가 진행되고 있다. 그러나 현 상황에서 엘리베이터의 고려는 대부분 설계단계에서 이루어지나 비상대응계획 차원에서의 명확한 가이드라인 없이 설계자의 판단에 의하여 진행된다. 이를 위하여 본 연구에서는 기존 연구 문헌과 설계자들에 의하여 현재 고려되어지는 요소를 인적, 환경적, 전략적인 고려요소로 구분하여 검토하였다. 엘리베이터 피난에 고려되는 요소를 목적과 기능, 역할에 따라 하위 단계위 구성요소를 설정하였으며 각각의 요소는 상위 요인에 종속되는 것으로 설계하였다. 종합적으로 볼 때 엘리베이터 피난에 있어서의 많은 요소가 고려되어지며, 각각의 요소는 계단과 피난층 등의 피난수단의 복합적인 이용에 따른 피난설계단계뿐만 아니라 유지관리단계에 있어서도 영향을 끼치는 것으로 분석되었다.

최근 축조되고 있는 건축물의 경우 고층을 넘어서 초고층화가 되어가는 현실이다. 이러한 사항에서 현재 이용되고 있는 피난계단 및 수평 수직 피난에서는 고층화가 되어가는 건축물에서의 피난이 어렵다는 점을 인지하여 고층건축물의 필수요소인 EV를 통한 피난계획 작성에 기초적인 자료가 되기 위하여 국외적으로 연구중인 EV피난에 대해서 알아보고 또한 그 내용을 토대로 현재 국내에서의 EV피난에 대한 효율성을 제시하여 향후 고층건축물의 피난계획에 일부분에 기초자료가 되고자 한다.

The study analyzes the appropriate number of people per a household by applying an evacuation simulation to a 27-floor apartment in accordance with the NFPA 101 standard. The results of the analysis are as follows. First, if there are three people residing in each household, there would be 156 households in total, of which 85.25% were evacuated within 5 minutes. Second, 208 households with 4 residents were evacuated within 5 minutes. Third, if there are five people residing in each household, there would be a total of 260 households and 71.92% of residents were evacuated within 5 minutes. Lastly, 62.82% of the 312 households, each consisting of 6 people, were evacuated within 5 minutes. Measures to reduce evacuation time include determining the width of the stairs according to the number of people indoors, the number of floors in the building, the slope of stairs, and the users' characteristics, the design reflecting the ventilation conditions of the stairs, the installment of outdoor evacuation stairs, two-way stairs, evacuation lift, and the installation of an evacuation safety zone for people to evacuate outside of the building in the middle floors. In addition, measures, such as the mandatory installation of automatic emergency door open-close device to the rooftop, are required to facilitate rooftop evacuation.

This study focused on the construction of Korean Evacuation load Model for reflecting Korean Evacuation behaviors. For the purposes, several evacuation experiments are executed according to the ages, and the level and types of disabilities. We accumulated the data on the evacuation velocity and behavior patterns according the ages, and the level and types of disabilities. From these results, we proposed the Korean Evacuation Load Model and compared with several popular evacuation simulation model such SIMULEX. As results of these studies, we found the possibility of construction of Korean Evacuation Simulation System based on the Korean Evacuation Model including the evacuation velocity and human behaviors.

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.
