  • Fire load in buildings greatly contribute to the time and scale of fire according to the type and quantity of the fire load. Because bookstores have a large quantity of fire load compared with other buildings which may lead to large scale fires, however, their heat release characteristics have been hardly investigated. In this study, to obtain the data applicable for the performance-based fire safety design of bookstores, the specimens representing stacked fire loads were heated in a furnace in compliance with the standard heating curve of ISO834-1:1999 to investigate their heat release characteristics. From the experiment result, the combustion velocity and heat release rate required for performancebased fire safety designs are obtained.

  • 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. Based on the results, it has reviewed fire safety when a fire accident occurs on the large bookstore and suggested peak heat release rate per burning surface, fire growth rate, etc of the live fire load required for fire safety design in bookstore.

  • 건축물의 적재가연물 특성은 성능위주 화재안전설계를 수행함에 있어 중요한 인자이다. 본 연구에서는 서점의 성능위주 화재안전설계에 이용할 목적으로 적재가연물을 대상으로 연소발열성상을 측정하기 위한 화재실험을 행하였다. 실험에서는 서적과 서가의 일부분을 재현한 시험체를 내화로에 넣고 ISO834 표준가열곡선에 따라 가열하여 화재 최성기에서의 연소성상을 파악하였다. 그 결과, 서적은 외부 가열을 받으면 표면연소 후에 탄화하여 주위에 고온이 형성되어도 열분해가스의 방출량이 증가하지 않는 것으로 파악되었다.

  • Purpose: Fire load analysis was conducted to secure basic data for evaluating fire risk of educational facilities. In order to calculate the fire load through a preliminary survey, basic data related to the fire load of school facilities were collected. Method: The basic data were the definition and types of fire loads, combustion heat data for the calculation of fire loads. The fire load was evaluated by multiplying the combustion heat by the weight of the combustibles in the compartment when calculating the fire load. Result: As for the fixed combustible materials of A-elementary school, the floor was mainly made of wood, in consideration of emotion and safety in the classroom, music room, and school office, and the rest of the compartments were made of stone. The ceiling and walls were made of gypsum board and concrete, so they were not combustible. The typical inflammable items in each room were desks, chairs, and lockers in the classroom, and the laboratory equipment box and experimental tool box were the main components in the science room, and books, bookshelves, and reading equipment occupied a large proportion in the library room. Conclusion: 'The fire loads of A-elementary' schools according to the combustibles loaded were in the order of library, computer room, English learning room, teacher's office, general classroom, science hall, and music room.

  • 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.

  • 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 post office buildings in Japan. In this report, burning behavior of typical combustible objects in post office buildings are studied by measuring heat release rates of plastic palettes with and without postal envelopes or packages and special containers loading numbers of palettes. The test results suggest that dynamic heat release rate is highly dependent on the condition of palettes especially if they load appropriate amount of postal envelopes or not.

  • Lots of products stocked at a traditional market are made of rubbers, synthetic fibers and plastics which when on fire, emit high heat to easily ignite nearby inflammables. And shops are not divided by fireproof partitions but by combustible curtains, which contributes to a possibility of a conflagration. In this study, danger and weak factors on fire at a traditional market was analyzed. Non-existence of partition between shops and the height of piled inflammables are set as danger factors and change of extinguishing capacity of sprinklers was analyzed using fire dynamics simulator. As a result, it turned out that partitions between shops and high-piled inflammables reduced watering radius of sprinklers and increased the size of fire and distribution of temperature.

  • To improve the prediction result with enhanced reliability of domestic Performance-Based Design (PBD), actual scale fire tests were carried out on products made of plastics from sales facility combustibles. The commercial buildings were separated into single and multiple combustibles for the experimentation of fire spread caused by the sales shelves where the various combustible materials are displayed. A according to the maximum heat release rate, exposed area and weight of the combustible material, the results revealed a linear relationship of as 93% and 89%. In addition, analysis of the gas concentrations for various combustibles showed that $CO_2$ has a linear relationship, whereas the CO concentration indicated exponential function. These results can be applied to reliable fire source information in PBD of plastic fire source in commercial buildings. This may be applied as fire source information representative of a plastic fire in commercial buildings through additional experiment using the area of the shelf in actual commercial buildings.
