Abstract
Car combustion experiment was conducted by selecting 3 cars, medium sedan, large sedan and van, for modeling of heat release rate(HRR) on car fire at parking space. Lists of measurement are internal and external temperature, HRR, mass decrement, and according to the result of experiment, it is considered that it requires review of fire resisting capacity of structure by temperature characteristic of internal and external temperature, and location of parking space structure. as a result review of fire resistance is needed. Also, Total HRR, burning speed, and heat of combustion of car were secured, and modeling of HRR for each car classification was written by using HRR. As a result, error range of total calorific value between experimental value and model value was within 10%, and it proposed combustion characteristic DB by car classification for fire resistance design of parking space structure.
Key Words: Vehicle combustibles test; Vehicle fire modeling; Combustion properties
요지
주차공간 차량화재에 대한 열방출율의 모델화를 위해 중형승용차, 대형승용차, 승합차 3대의 차량을 선정하여 차량연소실험을 실시하였으며, 측정항목은 차량의 내외부온도, 열방출량, 질량감소량이다. 온도측정결과, 내화성능평가로서 적용되는 ISO 834곡선에 비해 높게 측정됨으로서, 내화성능의 검토가 필요할 것으로 사료된다. 또한, 차량의 총 발열량, 연소속도, 연소열 등 을 확보하였으며, 열방출율을 이용하여 차량별 열방출율의 모델화를 작성하였다. 그 결과 실험값과 모델값의 총 발열량의 오차범위는 10%내에 있었으며, 주차공간 구조물의 내화설계를 위한 차량종류별 연소특성 DB를 제시하였다.
핵심용어: 차량연소실험; 차량화재 모델링; 차량연소특성
