Abstract

This study evaluates the safety of an asylum through a fire simulation of building Type traditional markets. We derive the building's indoor temperature, use the observed variation in temperature gradient to calculate the temperature of the main structure, and finally compares the time required to attain the limit temperature of the structure its time of escape. To ensure improved security of the asylum, the government has proposed a fire-resistance improvement plan for the major structural parts of buildings are not safe with thickness of 0.01 m and 0.035 m. F.ire-resistance reinforcement for small - and medium-sized vehicles is more than 0.025 m, in thickness; moreover safety can be ensured for medium and large-sized vehicles fire using fire resistant reinforcement of over 0.035 m. Accordingly, in order to ensure the safety of an asylum, fire-resistant reinforcement measures may be considered.

본 연구는 건물형 전통시장의 화재 시뮬레이션을 통해 실내온도를 도출하여 온도구배를 이용하여 주요구조부의 온도를 산출하여 구조체 한계온도에 도달하는 시간과, 피난 시뮬레이션을 이용하여 도출 된 피난완료시간을 비교하여 피난안전성을 평가하였다. 피난안전성이 확보되지 않는 건축물의 주요구조부재에 내화보강을 0.01~0.035 m 두께로 실시하는 것을 개선안으로 제시하여 피난안전성을 확보하고자 하였다. 소형과 중형은 내화보강이 0.025 m 이상일 때, 중대형과 대형은 0.035 m 이상 보강시 안전성이 확보되는 것으로 나타났다. 이에 피난안전성의 확보하기 위해선 내화 보강이 적용되어야 할 것으로 판단된다.
