In Korea, buildings are becoming skyscrapers due to restrictions on land. The performance-oriented design was introduced in 2009 for fire safety of such buildings, but the application of the combustible data through engineering design and experiment is a poor reality. Large buildings are used for complex purposes, especially since the density of the office facilities is high, the study conducted a study on the combustible materials of the office facilities and the thermal speed and fire load of the main combustibles of the office facilities were calculated.

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.

In the case of residential facilities, general fire scenarios cannot be applied. Becauseit is difficult to quantify due to the types of combustibles and various fire loads. Existing research conducting surveys of combustibles, but research on fire characteristics is insufficient. Therefore, in this study, an Excel macro that can be quantified by experimenting with the HRR experiments of sofa, drawer, mattress, chair, desk and TV, which are typical combustibles. As a result of experimenting 6 loading combustibles in domestic residential facilities by using a furniture calorimeter, values of 2,391.26kW appeared from the sofa, 1,891.80kW from the drawer, 1,778.95kW from the mattress, 1,104kW from the chair, 291kW from the desk, and 135.09kW from the TV. Also, by applying the α value of the fire growth rate by classifying fire-growing speeds at NFPA 72 (National Fire Alarm Code 2007, Annex B), the mattress can be defined as Very Fast, the sofa and drawer Fast, the TV Slow, the desk Slow, and the chair Medium.

The Fire growth rate(kW/s²) is significant impact on initial fire behavior in fire safety design of buildings. As a result of domestic existing combustibles, this study analyzed considering matters in techniques for calculating caloric values, and then made an investigation sheet. By utilizing written combustion sheets, the study could suggest a standard model at common houses and dense ones after getting caloric value information in dense ones. As a result, fire growth rate is experiment 1(0.01), experiment 2(0.0048), FDS(0.0072), MATSUYAMA equation(0.0144).

The burned patterns of fire are changed very diversely according to the direction of wind, conditions of combustibles, shape of buildings and so on in the fire scenes. And careful attentions are required on the determining of ignition point and fire causes. In this study, we examined that the burned pattern of fuel controlled fires and ventilation controled fires that impose a heavy burden on fire investigators, carbonized marks of floor, formed by flammable liquids, and combustion marks of falling firing materials through the fire cases. We suggest a proper fire investigation method.

본 연구는 건축구조물의 내장재 및 실내장식물 등의 연소 성상 DB를 바탕으로 화재 성상을 예측할 수 있는 기존 모델인 칼슨모델(B.Karlsson) 및 퀸티어리모델(J.G.Quintiere)을 비교, 분석하여 그 절차 및 차이점 등을 분석한 후 국내 가연물 연소성상 DB를 토대로 개구조건 및 건물구조 등을 고려한 화재성상 시뮬레이터 개발을 위한 기초 조사 자료이다. 조사 결과 칼슨모델과 퀸티어리모델의 차이점은 우선 초기 착화영역과 착화의 판단 및 연소면적 등에서 차이가 있었으며 향후 이를 기초로 실험 결과와 대비를 통한 분석을 수행 할 예정이다.

The surveying method for determine moveable fuel load estimates is presented. Two types of offices, open plan design and compartmented layout were surveyed and Data are presented for fuel load densities in ten office buildings. Office building fuel load in Korea range from 36kg/$m^2$ to 52kg/$m^2$ with 95% confidence level and represented mean 44.27kg/$m^2$. The results of the study presented the impact of the office layout and computer accessary contribution on the fuel load. In addition, a comparison of fuel load that found at this survey and that found at Fire Protection Dept., University of Maryland, U. S. A was made.

In this study, we have assessed the fire risk of Buddhist temples located in Youngdong area by means of fire loads of components. First, we categorized the components into Buddhist temples (Dae-Ung-Jeon, Pal-Sang-Jeon), Sam-Seong-Gak (Chil-Seong-Gak, San-Sin-Gak), a Buddhist temple dormitory (Sim-Geom-Dang, Seol-Seon-Dang), Lu, Il-Ju-Mun and then carried out a field survey. Then, we examined the area of each room, types as well as quantity and dimension of combustibles. The fire loads calculated in this way were 446.96 $kg/m^2$ for Buddhist temples, 331.71 $kg/m^2$ for Sam-Seong-Gak, 164.14 $kg/m^2$ for the Buddhist temple dormitory, 463.91 $kg/m^2$ for Lu and 1042.14 $kg/m^2$ for Il-Ju-Mun, thus showing Il-Ju-Mun with the biggest fire load. We speculate that this is because construction materials were similar in size and quantity to others albeit the area of Il-Ju-Mun is smallest.
