As population grows and urban facilities are concentrated in specific areas due to recent urbanization and industrialization, cities have structures vulnerable to both natural and man-made disasters. Most of these structures, whether buildings or residential houses, are left in a defenseless state if not given the appropriate check-up before they are built. The process of rapid urbanization without establishing the proper urban fire risk assessment will surely lead to disasters. This phenomenon occurred during the process of rapid urbanization and maybe said the result of chaotic urban expansion where modern urban infrastructure is not yet equipped in the city. Under the said circumstances, propagation processes of Korean urban fire cases were investigated to establish fire risk assessment system. Moreover, this paper explains the experiment performed for establishing urban risk assessment model. The said experiment was conducted using the new urban fire risk assessment model.

국내 화재사고중 화재가 가장 많이 발생한 발화지점은 생활공간이며, 이중 침실 및 숙박용 객실이 가장 높은 화재 발생 건수를 보이고 있다. 이처럼 주거시설, 청소년 수련시설 등 생활공간에서의 화재는 화재시 침대 매트리스에 의한 연소확대로 많은 인명 및 재산 피해를 발생시키고 있다. 본 연구에서는 생활공간을 구성요소중 침대 매트리스의 화재확대 위험성에 평가하기 위하여 실규모의 화재실험을 수행하고, 이를 분석하였다. 이러한 실규모 화재실험을 통하여 얻은 결과는 국내 성능적 화재안전 설계를 위한 기본적인 자료로 이용됨과 동시에 주거공간의 화재확산 방지 기술 개발에 기여할 수 있을 것으로 평가된다.

After train fire accident in Daegue, many research on train fire safety improvement have been carrying out. Since many alternative fire safety measures can be applied in our railway system, the effect of the each safety measure must be quantified prior to the safety investment. In order to estimate the effects of each safety measure quantitatively, fault trees and event trees are constructed in this study. Results can be applied for cost-benefit analysis or sensitivity analysis for safety measures in risk assessment process.

발열량은 화재현상을 이해하고 화재의 위험도를 평가하는데 있어서 가장 기본이 되는 물리량으로 화재강도를 나타내는 척도로 인식되고 있다. 발열량의 신뢰성은 화재 물성이나 공간화재 특성의 이해뿐만 아니라 화재해석을 통한 위험성 평가에 있어서 중요한 요소이기 때문에 측정의 신뢰성이 매우 중요하다. 본 연구에서는 수치해석 모델을 통하여 화재 발열량계의 배기덕트 구조에 따른 내부 유동특성을 파악하고자 한다. 해석결과를 바탕으로 각 측정점의 위치에 따른 상태오차 정도를 분석하고 산소소모법에 의해 계산된 발열량을 비교한다. 화재 발열량계의 수치해석을 통하여 발열량 산정의 오차특성을 평가함으로써 발열량계 설계 과정을 최적화하고 효과적인 발열량계 운영을 위한 기초자료를 얻는데 기여하고자 한다.

In Korea, fire hazard and risk analysis and response management planning related to existing decrepit buildings, including interior construction and architectural layout revision, due to various occupancy purposes have not been researched or established. Therefore, regulations and technical standards that can manage and reduce fire hazards and risks based on fire hazard analysis and evaluation are required. This study was performed based on a site survey and fire evacuation assessment including performancebased analysis in 3 actual existing buildings to find the life safety issues and provide improvement recommendations.

The fire risk and fire safety of four types of wood were comprehensively evaluated according to Chung's equation-XII. White ash, willow, fraxinus mandshurica, and sagent cherry trees were selected as test specimens. A cone calorimetery (ISO 5660-1) was used to examine the combustion characteristics of the test piece, and finally, the fire risk rating (FRR) was predicted using the fire risk index-XII (FRI-XII). The predicted fire performance index-X (FPI-X) and fire growth index-X (FGI-X) ranged from 469.03 to 1109.73 s²/kW and 0.0009 to 0.0280 kW/s², respectively. Additionally, the fire performance index-XI (FPI-XI) and fire growth index-XI (FGI-XI) ranged from 0.41 to 0.97 and 1.11 to 3.11, respectively. The fire risk index-XII (FRI-XII), representing a fire risk rating, showed that the fire risk of frasxinus mandsurica tree (FM) was very high at 7.60 (fire risk rating: D). And it was compared with Chung's equation-IX, fire risk index-IX (FRI-IX). The fire risk ratings according to FRI-IX and FRI-XII were generally high for willow and frasxinus mandsurica trees. Additionally, the results of FRI-XII and FRI-IX had a similar relationship, and the size of each fire safety rating closely matched each other.
