초고층 건축물의 수직성 증가는 더 긴 최소피난시간(Required Safety Egress Time, RSET)을 요구하게 된다. 초고층건물에선 계단을 통한 수직이동이 피난경로 상의 대부분을 차지한다. 본 연구에서는 고층 건물에서 반복된 3번의 대피훈련을 시행하고, 영상분석을 통해 피난경로 선택의 변화와 계단실 내 수직 보행속도-밀도의 함수관계를 분석했다. 또한 Pathfinder 피난시뮬레이션을 이용하여 단계적 피난의 방법에 따른 총 피난시간의 변화와 실제 훈련의 결과를 비교 분석하였다. 그 결과 반복적 피난훈련과 교육을 통해 특정 계단 이용률이 6.3%에서 39.5% 개선되었고, 각 피난경로별 피난시간도 단축됨을 확인하였다. 또한 계단실 내 수직 보행속도-밀도의 관계식이 기존의 연구결과와 매우 유사한 s = 1.004 ? 0.288D로 확인되었다. 단계적 피난의 방법에 따라 전층 동시피난에 비해 총 피난시간이 25% 이상 변화할 수 있음을 확인할 수 있었다.

The purpose of this study is to secure an evacuation time and to ensure safety by using an Ubiquitous Sensor Network computing when a fire breaks out at a super high-rise apartment housing. A super high-rise apartment housing that is a type of building to solve the problem of separation of the urban function and the phenomenon of hollowing out downtown has been on the increase, high-rise apartment housings occupying 52.7% of whole housings in 2005. However, if a fire breaks out, there would be serious damage since it accommodates many people and facilities as existence of vertical gigantism in the city. The architectural law in force has no clause on it which is universally applicable to general building, it is difficult to be applicable to a densely super high-rise apartment housing and there would be in danger of a resident's evacuation in the fire. Therefore, as a previous study to introduce an USN-based fire-warning facility and evacuation equipment, this study shows the improvement way after analyzing factors that are barriers to evacuaee's behavior of a super high-rise apartment housing and also shows establishment of the grade of vertical evacuation rank by SimuleX, one of the best computer simulation program.

연구목적: 화재 발생 시 요양병원은 재실자 특성, 건물의 취약요소 등으로 인해 피난하는데 상당한 제약이 따르며, 요양병원 내 환자를 대피시킬 수 있는 제품 개발을 하여 피난의 효율을 높이고자 한다. 인공지능 기반 자율주행형 재난약자 대피 도움장치를 개발하였고, 효율적으로 사용하기 위해 화재 및 피난 시뮬레이션에 활용하였으며, 환자 대피를 돕는 조력자에 대한 분석을 연구하고자 한다. 연구방법: 화재 시뮬레이션을 통해 시간 별 연기 성상 분석을 하였으며, 최종적으로 주간 야간에 따른 조력자수를 입력하고, 피난시뮬레이션을 활용하여 피난 완료 시간을 비교 분석하였다. 연구결과: 재난약자 대피 도움장치를 활용하였을 경우 대피 시간은 20%이상 단축이 되는 것을 알 수 있었으며, 주간 대비 야간의 화재 발생 시 대피 시간은 70% 가까이 늦어짐을 알 수 있었다. 결론: 수평·수직 대피 도움장치를 실제 화재 상황에서 효율적으로 활용할 경우 상황에 맞는 전략이 필요할 것으로 판단된다. 추후 화재 상황별 시나리오에 따른 대피 매뉴얼을 개발함으로써, 수평 대피 도움장치 및 수직 대피 도움장치에 대한 활용에 대한 내용을 바탕으로 피난의 효율성이 증대될 것으로 기대된다.

In the event of a fire in a high-rise building, rapid evacuation through the stairwell is a very important factor in rapid evacuation. However, in the event of an actual fire, most of the occupants evacuate at the same time, resulting in a stay in the stairwell, reducing the evacuation speed. In Korea, conditions for buildings are created to evacuate quickly and safely while introducing performance-oriented designs to solve these problems, but there is no research data related to the evacuation speed due to joining in the event of vertical evacuation. Therefore, in this study, by analyzing the experiment conducted at W University in Japan, the density-speed relationship when staying in the staircase room was derived, and the regression equation was derived based on the results.

지하철 역사 화재는 다수의 인명피해를 동반한 대구 지하철사고 이후 지하철 차량 내장재, 지하역사의 제연 시스템과 승객이 지상으로 탈출하기 위해 필요한 피난시간 등과 같은 기존 시스템에 대한 적정성 논란을 가져왔다. 기존의 제연설비는 화재 시배기 용량과 역사 시설구조의 복잡성으로 인한 제어방법의 한계가 따른다. 특히 지하철 역사 화재는 지중에서 지상으로 대피하는 형태로서 이는 부력으로 인한 연기의 이동방향과 피난방향이 같아지게 되므로 피난자들이 일반화재보다도 더욱 많은 연기의 영향에 노출되어져 버리는 결과가 발생한다. 본 연구에서는 하향식 피난 동선을 설계하여 피난완료시간의 단축 및 연기 층으로부터 피난자들을 격리시켜 희생자를 줄일 수 있는 방안을 제안하였다.

화재 발생 빈도는 높으나 인명 피해보다 재산 피해에 초점이 맞추어져 있으며 동시에 피난 시뮬레이션이 성능위주설계를 하는 특정소방대상물을 중심으로 이루어지는 현실 속에서 소규모 공장은 피난 안전 연구의 사각지대에 존재한다. 또한, 기존의 연구에서 제시하는 방법들은 안전을 개선하는 데 큰 시설・설비 및 구조의 변화를 요구한다. 이 연구에서는 피난 시뮬레이션을 통해 공장 작업대의 위치 변화만으로 RSET이 달라지며 대피 가능 여부에도 차이가 있음을 밝혀냈다. 작업대를 세로 형태로 배치하는 것이 가로 형태 배치 대비 이동 거리를 줄여 RSET을 줄임을 알 수 있으며 가장 RSET이 짧은 것은 '세로-가로'의 복합형이었다. 연구 결과는 예산 등의 제약으로 필수적 안전 설비를 제외한 추가적 투자가 어려운 소규모 공장에서 RSET을 줄일 수 있는 실용적 대안을 제시했다는 점에서 의의가 있다.

Recently, many patients in a hospital are threatened life by fire disaster. Because many patients like vulnerable people have more evacuation problem than ordinary person. So a patient who can escape by oneself with walking assistance device like crutches or wheelchair and another patient who can't escape by oneself are should be supported safety technologies and service. Earlier research of 'hospital evacuation' led by actual experiments or computer evacuation simulation. Actual experiment is effective to gain credibility of result but it is difficult for patients to experiment repeatedly and it requires consideration for spatial problem and economic problems. Although computer evacuation simulation have been used to solve these problems, almost have concluded only results based on velocity without evacuation device. In this study, evacuation results with support device application or not are analysed used by computer evacuation simulation based on MAS(Multi Agent System). As a result, it is drawn through proof of efficiency of evacuation device in the vertical space like stairs that can improve the evacuation plan for vulnerable people in the hospital.

With the "Fire Protection Building Plan" of the Building Center of Japan as a sample, actual evacuation plans used for large scaled and multi-storied buildings are analyzed. Sufficient number of samples were classified into 6 categories. For room evacuation, time to pass through the exit was the most critical point for larger spaces and movement time in the room was the key for smaller evacuation object zone and less number of evacuees. Seen from the location of fire breakout point, it was witnessed that the numbers of crowding at the exits of the fire escape staircase are serious for floor level evacuation. For vertical traffic line, it was actually proved that time to fire escaping floor is problem of higher buildings. It was also proved that special evacuation methods are in practical use in many buildings in japan.

This study, in order to evaluate the safety of evacuation by comparing and analyzing the RSET according to the slope change of the ramp, which is a vertical evacuation route in case of fire in a high school building, Evacuation simulation was run the Pathfinder program changed the slope of the ramp to 10°, 15°, and 20° for each male students and female students. In the case of female students, it was analyzed that when the final RSET slope was 15°, 25.7 seconds were shorter than when 10°, and 4.2 seconds were shorter than when 20°. Male students also found that when the final RSET slope was 15°, 23.8 seconds were shorter than when 10°, and 5.4 seconds shorter than when 20°. It was analyzed that even if the number of participants was increased and the evacuation simulation was executed, the safety of evacuation could be improved when the slope of the slope is 15° as the RSET when the slope of the slope is 15° is shorter than that of 10° and 20°.

As there are the elderly who have difficulty in evacuating themselves, it is necessary to develop architectural and institutional planning for nursing homes that can minimize disaster damage. The purpose of this study was to suggest the improvement plan by grasping the current status of nursing homes on planning aspects such as floor plan type, spatial layout, and evacuation route through 14 case studies in Cheongju city in terms of disaster safety. The results of this study were as follows; the most common plan type was the grouped-corridor type difficulty in securing evacuation routes. The circulation corridor type is need to be considered because it is possible not only to secure evacuation and nursing routes, but also to create a hanging around corridor for the elderly with dementia. Second, if there is a risk of flooding due to the location, the living room should be placed on the 2nd floor or more. In particular, a kitchen should be placed not adjacent to the entrance and the vertical evacuation route. Third, the horizontal evacuation route should be arranged differently depending on the floor plan type. For vertical evacuation routes, it is necessary to install outdoor stairs or ramps considering the evacuation characteristics of the elderly. In addition, the institutional aspects should be considered to ensure the safety of disasters.
