A Study on the Fire Resistance Design of Buildings Considering the Fire Load Energy Density

요약

본 연구의 목적은 성능위주의 화재안전설계법에 따른 구획실 용도별 요구내화시간산정을 실시함으로써 현행 내화성능기준의 문제점도출 및 개선방향을 제시하는 것이다. 내화성능기준에 대한 검토를 위해 본 연구에서는 현재 국내의 시방규정에 의해 결정된 요구내화시간과 등가시간공식에 의해 산정된 화재노출상응시간과 비교하였고, 화재노출상응시간을 산정하기 위해 화재하중밀도, 환기계수, 구조재료의 열적특성 그리고 구획실 형상치수 등을 조사하였다.

Abstract

The main purpose of this study is to raise the point at issue and to propose reform direction about the current performance criteria of fire resistance through the examination of the fire resistance required for each use of compartment by using performance-based fire safety design method. To examine the performance criteria of fire resistance, this study compared the equivalent time of fire exposure which was calculated by using time-equivalent formulae with the required fire resistance time determined by existing prescriptive code, and surveyed factors such as the fire load energy density, ventilation factor, fire compartment materials and fire compartment geometry in order to calculate the equivalent time of fire exposure.

Key Words: Performance-based fro safety design, The performance criteria of fire resistance, The Equivalent time of fire exposure, Field survey, Fire load energy density
