  • 최근 건축물의 초고층화에 따른 커튼월 시공에 따라 유리의 비중이 증가하고 있다. 커튼월 구조는 바람, 지진 등에 취약하며, 화재 안전성에 있어서도 취약할 것이라 판단되므로, 국내외 건축용 유리 및 커튼월의 안전기준에 대한 조사를 실시하였다. 그 결과 국내의 유리 기준은 단열 및 내풍압 성능에만 집중되어있으며, 화재 및 지진, 안전성능에 대한 기준이 미비하며, 커튼월에 대한 안전대책은 전무한 실정이다. 따라서 외국의 사례와 같이 초고층에서 커튼월의 안전성능을 고려한 설계프로세스나 안전 기준의 세부화가 필요하다고 판단된다.

  • The goal of fire prevention research is to eliminate fires as a cause of fatal accidents and there are two main areas of research. One is to prevent flame propagation during in-flight and it addresses fire hazards. The other is to minimize the possibility of flame penetration or fuselage burn-through and it aims toward post-crash survival include crash protection, emergency evacuation and post-evacuation survival. Civil aviation authorities world-wide are trying to identify threats and measure performance for fire prevention. The results of research are standardized and given as general directions of test methods. This paper has prepared to study and present the means of compliance to the fire prevention requirements and applicable test methods.

  • The current status of Performance-Based Design (PBD) implemented in 4 wide areas (Seoul, Gyeonggi, Incheon and Busan) over the past 5 years was reviewed with regard to the number of PBD implementation and target buildings. Then, detailed status related to fire scenarios, input information for fire simulation, and grid size were analyzed with the pre-review for the PBD. As a result, the domestic PBD was mainly applied to the mixed occupancy. In the fire simulations performed on the identical fire scenario and fire space, the maximum heat release rate (HRR) varied significantly depending on the PBD designer. Various combustibles were also considered for the identical fire source, and their combustion properties also showed considerable uncertainty. In addition, the applicability of accurate input information for predictive models of heat and smoke detectors was examined. Finally, the average grid size for the fire simulation using Fire Dynamics Simulator (FDS) was analyzed, and the improvement of PBD to minimize designer dependency was proposed.

  • In this study, we considered the fire risk assessment of the temple using fire loads and the classification of combustibles. The building construction materials were classified as walls, beam-columns, floorings, ceiling panels and the loading combustibles were classified into fixed materials and movable materials. As a result, we confirmed that the total fire load of the Palsangjeon was $368\;kg/m^2$. The building construction materials accounted for approximately 93.8 percent of the total fire load and the loading combustibles accounted for approximately 6.2 percent.

  • Forest fires inflict great losses of human lives and serious damages to ecological systems. Hence, numerous fire detection methods have been proposed, one of which is fire detection based on sensors. However, these methods reveal several limitations when applied in large spaces like forests such as high cost, high level of false alarm, limited battery capacity, and other problems. In this research, we propose a novel forest fire detection method based on image processing and correlation coefficient. Firstly, two fire detection conditions are applied in RGB color space to distinguish between fire pixels and the background. Secondly, the image is converted from RGB to YCbCr color space with two fire detection conditions being applied in this color space. Finally, the correlation coefficient is used to distinguish between fires and objects with fire-like colors. Our proposed algorithm is tested and evaluated on eleven fire and non-fire videos collected from the internet and achieves up to 95.87% and 97.89% of F-score and accuracy respectively in performance evaluation.

  • This study shows the difference between groups with multivariate analysis of fire prevention activities, special investigations of fire safety, and fire safety management according to the management method of apartment houses and the inspection of firefighting facilities. The results of the analysis are as follows. First, there was a significant difference in fire prevention activities according to the quality of inspection of firefighting facilities. This means that fire prevention is high if the fire safety manager's ability to inspect firefighting facilities is excellent and the fire safety inspection is conducted in accordance with national fire safety standards and checklists. Second, there was a significant difference in the fire safety special investigation according to the management method of the apartment buildings. The manual operated by the management entity and the management entity's management and execution help the organization members to expedite work. This expedition of work creates a high possiblity to get a good evaluation from the special investigation of fire safety. Third, analysis of fire prevention activities showed a significant interaction between the inspection of firefighting facilities and the management method of apartment buildings. The analysis shows that that there is a positive correlation between the level of fire prevention and both the fire safety manager's ability to inspect firefighting facilities and the degree to which the inspection is conducted to meet national fire safety standards.

  • 최근 건축물에서 공동주택의 비율이 증가하고 있으며 동시에 공동주택의 화재비율도 증가하는 경향을 보이고 있다. 또한 화재 시 인명 피해의 주원인인 가연물은 소재가 다양화되고 있으나 안정성 보다는 디자인, 기능성에 치중되어 그에 따른 화재 위험성도 커져가고 있다. 따라서 본 연구는 전보의 실내장식물에 이어 공동주택에서 많이 사용되어지는 적재가연물을 가연물 조사를 바탕으로 선정하여 Furniture Calorimeter를 이용해 그 연소특성을 알아보았다. 그 결과, 소파가 타 시료에 비해 화재 시 높은 위험성을 나타냈으며, 일본건축학회에 발표된 데이터와 비교한 결과 소파의 데이터가 유사한 것으로 나타났다.

  • 최근 화재시뮬레이션을 이용한 화재위험성평가를 많이 실시하고 있다. 이에 따라 화재시뮬레이션에 대한 중요성도 강조되고 있으나, 국내에서는 화재시뮬레이션에 대한 신뢰성에 대한 연구는 미흡한 실정이다. 따라서 본 연구에서는 단일구획의 화재실험을 실시하고 각 가연물의 연소 특성 실험을 적용한 FDS와 일반적으로 구동하는 FDS의 비교를 실시하여 FDS의 신뢰성을 알아보았다.
