Abstract

It is necessary to enhance its availability and reliability of performance based fire design of building with various type of database such as experiments, survey and fire properties and so on. In order to utilize to the performance based fire design, the present study has been performed a series of experiments to investigate the burning characteristics of building materials for two types of interior board and three types of interior louver. The burning test has been also conducted for different thickness because it may show different characteristics of burning behavior such as flame spread rate and flame propagation time. The result shows that the effective heat release per unit mass of interior materials were almost constant with 15.3~16.9 MJ/kg regardless of its thickness while the peak heat release rate and maximum $CO_2$ concentration was varied with thickness.

건축물의 성능위주 소방설계의 활용성 및 신뢰성을 향상시키기 위해서는 다양한 화재실험 및 조사 등을 통해 가연물의 연소물성에 관한 광범위하고 다양한 데이터베이스가 필요하다. 본 연구에서는 건축물의 성능위주 소방설계에 활용하기 위해 건축물의 내장용 판재 2종과 내장용 루버 3종을 대상으로 연소시험을 실행하여 연소발열특성 등을 파악하였다. 또한 내장용 판재는 그 두께에 따라 최대열방출률 등 연소발열성상에 차이가 발생할 가능성이 있으므로 판재의 두께에 따라 연소시험을 수행하였다. 실험결과 내장재 판재 및 루버의 단위연소량당 평균발열량은 15.3MJ/kg~16.9MJ/kg이었고, 내장용 판재의 평균최대열방출률과 평균최대이산화탄소 농도는 판재의 두께에 따라 차이가 있는 것이 확인되었다.
