본 연구는 건축물의 초기화재성상의 주요인자인 화재성장율 예측을 위하여, 일본 송산(松山)모델을 사용하여 예측값을 도출한 결과, 화재성장율은 $0.0144t^2$로 나타났다. 또한 이를 실규모실험(ISO-9705)와 FDS 해석값과 비교한 결과, $Q_{peak}$을 고려한다면 신뢰할 수 있다고 판단 할 수 있지만 약100초 이상의 결과에서는 환기인자 등에 관한 변수에 대한 고려가 필요할 것으로 판단된다.

Purpose: In order to secure a specific fire diffusion model, this study compares and analyzes the NIST UL standard application scenario and the performance-oriented design application scenario and examines the difference between the fire diffusion model and the surface fire model. Method: Temperature, visibility, and CO sensors were installed for each scenario using FDS, and the two scenarios were compared and analyzed through the changes. Result: As a result of analyzing the temperature, visibility, and CO for each scenario, the NIST UL standard application scenario is very similar to the actual fire, and the performance-oriented design application scenario shows a harsh fire situation. Conclusion: When designing fire safety for large buildings such as distribution warehouses, it is important to prepare comprehensive fire safety measures in consideration of both actual fire and harsh fire conditions.

국내 재래시장 상가건축물은 타 상업지역 보다 노후화된 상업건축물이 상대적으로 많으며 밀집도 또한 높다고 할 수 있어 화재발생 시 화재확산 속도가 빠르고 화재진압이 어려워 인명 및 재산 피해의 가능성이 크다고 할 수 있다. 이에 따라 정부에서는 재래시장을 특정관리대상으로 지정하여 정기적으로 점검을 하고 있으나 소방시설에 비해 상대적으로 피난계획 및 피난설비에 대해서는 적절한 성능평가 및 점검이 이루어지고 있지 않고 있다. 이에 따라 본 연구에서는 대구시 소재의 특정관리대상으로 지정된 재래시장 상가건축물을 조사하여 재래시장의 평면유형분류를 하였고, 각 유형이 가지는 특성을 분석하였으며 대상건축물 피난설비의 실태조사를 통해 경년변화에 따른 설비의 노후화 특성을 분석하였다.

The Installation, Maintence, and Safety Control of Fire-fighting Systems Act of South Korea regulates that over 30-storey high-rise buildings including underground spaces should vitally perform the Performance-based Design to minimize property damage and personal injury as a fire risk assessment in advance. Therefore a PBD designer such as a fire safety professional engineer evaluate occupant's life safety by a scientific methodology. In order to evaluate the life safety, fire safety designers calculate the Required Safety Egress Time (RSET) which does not have the legal criteria regarding the standard method of calculation yet. So this way has been showing different results depending upon the designer's choice, knowledges and experiences. In this study, RSET calculation methods by six designers respectively were analysed from the thirteen reports of real performance based design projects conducted in Busan for a last five years. In particular, the Response Time calculation methods which have the most powerful effect for figuring the RSET are compared with the other designer's to deduce an error value.

Sandwich panels which are having the both sides are bonded with a heat insulating material with an iron plate are used as factories, warehouse structures as advantages of convenience in construction at economic efficiency of material cost. However, in a panel structure constructed by continuous joining of sandwich panels, a joint portion where a panel and a panel are connected is generated. The joint part is a part which is easily vulnerable to fire because flames easily flow into the melting and deformation of the iron plate during fire. The flames flowing into the panel induce diffusion of fire by rapid burning, causing damage of human life and property. In this research, we developed a flame spread prevention plate to prevent spreading of sandwich panel. This is an improvement of the workability by the anti-spreading construction method of the existing previous research, it can be applied independently to the connecting part where the panel and the panel are coupled, designed to prevent inflow and spreading of flame did. The actual fire test of the test method of KS F ISO 13784-1 of the sandwich panel specimen was conducted and the burning behavior corresponding to the presence or absence of application of the flame spread prevention plate was grasped at the panel connection part and its effect was measured. Inserting a fire spreading plate into the test result panel connecting part is measured by delaying the flashover, prevention of collapse of the specimen, and temperature rise of the opening, effectively improving the fire safety of the panel structure It was confirmed as a method that can be secured. It is judged that panel structure will contribute to ensuring fire safety by applying the fire spread prevention construction method of various methods ensuring the workability and economy of panel connection vulnerable to fire.

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.

In Korea, performance-based fire safety designs are being discussed to deal with the various risks of fire in complex and diverse types of structure. However, performance-based fire safety designs are not actively employed because it is difficult to estimate the fire characteristics related to the various factors in buildings. In this study, real scale fire tests were conducted based on fire severity levels and fire loads provided in He New Zealand Building Code, in order to use the results as guidelines and fundamental data for performance-based designs. In the real scale fire tests conducted in a 10MW full-scale calorimeter, wood cribs were placed in a $2.4(L){\times}3.6(W){\times}2.4(H)m$ mock-up of a compartment which had one $0.8(L){\times}2.0(H)$ opening for different fire loads and heating was continued until all of the wood cribs were burned down. The heat release rate started to increase rapidly 90 seconds after the wood cribs caught fire. In the test with a fire load level 1, the maximum heat release rate of 4743.4 kW was reached at 244 second. In the test with fire load level 2, a maximum heat release rate of 5050.9 kW was reached at 497 second. In the test with fire load level 3, a maximum heat release rate of 4446.9 kW was reached at 677 second.

1999년 씨랜드 청소년 수련원 화재로 19명이 사망하여 샌드위치 패널의 위험성이 대두되었으며, 2008년도 이천 냉동창고 화재 그리고 최근 2009년 11월 19일에도 샌드위치 패널로 건축된 물류창고에서 화재가 발생하였다. 이러한 샌드위치 패널로 시공된 물류창고 등의 화재는 확대가 빠르므로 난연재 소재의 샌드위치 패널의 필요성에 대한 관심이 높아져 가고 있다. 따라서 본 연구에서는 폴리스티렌 폼을 심재로 한 샌드위치 패널의 장점에 난연성을 부과하여 화재 안전성을 도출하는 하고자 한다. 샌드위치 패널의 심재로 주로 사용되어지는 EPS 비드에 저가의 물유리를 코팅하여 난연성을 도출하고자 한다. 2차 발포 성형시에 물유리가 고온의 스팀에 씻겨 내려가지 않고 남아서 난연성을 나타내도록 하는 것이 목표이다.

The occurrence of fires in heavily populated multiplex buildings is a serious concern. It causes a great threat to many people and a serious social problem. Whenever this kind of fire happens, the authorities are busy preparing partial countermeasures to control the crisis situations. Luckily, the government has enforced a special law regarding safety supervision of majority-used buildings to prepare the basic countermeasures for the buildings' safety. Recently, the multiplex buildings which have multi type compounds have increased in size by getting bigger and bigger. As there are many people who would need to escape and the complicated structures like mazes in buildings of this type, it is not only difficult to prevent a fire but also easy to cause a large loss of lives. For a better fire safety supervision of the buildings, there needs to be passers and owners' good sense of safety, fire proof of the buildings and education of the fire authorities.
