Fire Risk Analysis on Buildings Considering Fire Spread and Total Floor Area

Abstract

Fire risk analysis models utilized for the fire risk assessment of domestic structures do not usually take into account flame spread and building size. Therefore, in this study, the effect of the building size on flame spread was investigated. Results showed that the frequency of occurrence of fires increased when the building has 11 or more floors. Additionally, the rate of occurrence of small-scale fires also increased when the total floor area was greater than or equal to 1,000 m². From the risk analysis, the fire risk of health care, medical, and recreational facilities were calculated to be 25.7 × 10^-3, 4.29 × 10^-3, and 0.91 × 10^-3 persons per year, respectively. As such, these were classified as high-risk facilities.
