화재시 재산과 인명의 피해를 최소화하기 위하여 건축물의 규모 및 용도에 따라 방화구획을 설치하여 화재 확산을 방지하도록 제도화 되어 있다. 방화구획의 개구부에는 방화문이 시용되며, 이러한 방화문의 성능기준은 국토해양부 고시로 규정되어 있다. 현재 방화문에 대한 국내 기준은 비 차열성능 위주로 되어있으며 복사열로 인한 화재확산 위험성에 대한 기준은 제시되고 있지 아니하다. 이에 본 연구에서는 방화문의 구조 및 재료별 복사열을 측정하여 복사열에 의한 화재확산 위험성을 확인하고 방화문 성능기준 추가 필요성을 제시하고자 한다.

본 연구에서는 복사열에 노출된 소방용 방수복의 열적 특성에 대한 실험을 수행하였다. 실험결과 소방용 방수복의 노출시간에 따른 표면의 온도상승은 노출거리가 가까울수록 급격히 일어났다. 또한 복사열유속이 클수록 표면의 온도가 높으며, 정상상태 도달시간은 짧게 나타났다. 소방용 방수복의 노출거리가 멀어질수록 표면의 온도는 급격히 감소하며, 전면과 후면의 온도차도 감소하였다. 복사열유속이 증가할수록 안전노출거리가 증가하였다. 따라서 소방대원의 안전을 위해서는 복사열원으로부터 일정거리이상 떨어져 작업하여야 할 것으로 사료된다.

The purpose of this study is to enhance heat insulation effect and to decrease fire hazard by attaching aluminum foil to expanded polystyrene, which is mainly used for insulating materials, to have fire retardant. The result of the test confirmed that the insulating materials, expanded polystyrene of $10kg/m^3$ and $14kg/m^3$ of density attached aluminum foil on both sides, showed 12%, 14% of improved heat transfer coefficient respectively compared to existing expanded polystyrene of the same density. Besides, they met all the standards for the testing of heat release and gas hazard. On the other hand, the one made of general expanded polystyrene could not meet the standards of the heat release test and the gas hazard test.

Heat release characteristics of live fire load are an important parameter for performance oriented fire safety design of a building. While investigations have been carried out on the fire load and its burning behavior in office, residential and commercial buildings and so on, little effort has been paid for the rational treatment of fire load in bookstore. In this report, burning behavior of typical combustible objects in bookstore are studied by measuring heat release rates of bookshelf with book.

In order to investigate the generation of carbon monoxide and heat loss of incomplete combustion in compartment fires, an experiment was conducted in a small scale compartment by using methanol as a fuel. The concentration of carbon monoxide and the toxicity parameter showed high values when the mass air - to - fuel stoichiometric ratio is under 1.0. The constitution of the combustion gas was showed to estimate it from the . The heat loss due to incompleteness of combustion is about one third of heat of combustion in case of under 1.0.

The characteristics of heat energy distribution on the fire-proof clay with microwave heating drying are numerically investigated using finite element method. The modelled regular hexahedron chamber$(50cm\times50cm\times50cm)$ filled with air consists of vertical heat source and sink walls, a fire-proof clay model, and adiabatic plates on the top and bottom walls. With different geometrical aspect ratios of the fire-proof clay model, the heat energy distribution is throughly investigated. The model gave a good prediction of the microwave heating characteristics of fire-proof clay. The optimal shape of the fire-proof clay for given chamber geometry and microwave power is analyzed.

본 논문은 화재발생시 열감지기가 오동작하는 특성을 열방출률(Heat Release Rate : HRR)을 이용하여 경계값을 정량적으로 나타내고 그 경계값을 기준으로 감지기의 오동작 영역을 분석하였다. Crib 형태의 목재를 가지고 small-scale의 화재실험을 통하여 화재감지기의 동작시간 등을 측정하였고 이를 이용하여 화재감지기가 동작하는 순간의 HRR을 계산하였다. 화재실험으로부터 얻은 변수를 가지고 화재감지기가 오동작하는 HRR의 경계값을 계산한 결과 정온식 감지기는 20.24 kW 차동식 감지기는 13.59 kW로 나타났다.

This paper proposes a nonlinear computational modeling approach for the behaviors of structural systems subjected to fire. The proposed modeling approach consists of fire dynamics analysis, nonlinear transient-heat transfer analysis for predicting thermal distributions, and thermomechanical analysis for structural behaviors. For concretes, transient heat formulations are written considering temperature dependent heat conduction and specific heat capacity and included within the thermomechanical analyses. Also, temperature dependent stress-strain behaviors including compression hardening and tension softening effects are implemented within the analyses. The proposed modeling technique for transient heat and thermomechanical analyses is first validated with experimental data of reinforced concrete (RC) beams subjected to high temperatures, and then applied to a bridge model. The bridge model is generated to simulate the fire incident occurred by a gas truck on April 29, 2007 in Oakland California, USA. From the simulation, not only temperature distributions and deformations of the bridge can be found, but critical locations and time frame where collapse occurs can be predicted. The analytical results from the simulation are qualitatively compared with the real incident and show good agreements.

This study was done to calculate the specific indicators of Fire-Heat Pattern Identification and Yin Deficiency Pattern Identification settled by tentative Korean Standard Differentiation of the Symptoms and Signs for Stroke. The subjects were 764 hospitalized patients with stroke, and a list of registry was made for each of them. Frequency and Correlations among Fire-Heat and Yin Deficiency indicators were studied. Fire-Heat pattern group included 175 patients out of 764, Yin Deficiency pattern group included 103 patients out of 764. Among the indicators of Fire-Heat pattern, those, in order of highest frequency, were 'heat vexation and aversion to heat', 'reddened complexion', 'thirst'. Among the indicators of Yin Deficiency pattern, those, in order of highest frequency, were 'dry mouth', 'red tongue', 'fine and rapid pulse'. Among the Fire-Heat pattern indicators, 'yellow fur' and 'thirst', 'heat vexation in the chest' and 'vexation and insomnia' showed most significant correlation. Among the Yin Deficiency pattern indicators, 'aphtha or tongue sore' and 'heat in the palms and soles', 'red tongue' and 'dry fur' showed most significant correlation. 'Reddened complexion', 'dry eyes', 'surging and parid pulse', 'heat vexation and aversion to heat' are classify between Fire-Heat pattern and Yin Deficiency pattern. 'Surging and parid pulse', 'Reddened complexion' are mostly representative of Fire-Heat pattern and 'fine and rapid pulse' are mostly representative of Yin Deficiency pattern.
