요약2 For the past decade, South Korea had experienced catastrophic building fires, which resulted in consider-ably
high number of casualties. This motivated research to develop fire-safe wall assemblies. In this study Fire Risk Analysis
(FRA) is conducted as part of the project designing phase to ensure fire safety of the final product. Traditional approach
was to consider fire performance at the end of the designing stage, when PASS/FAIL fire test results are required to be
submitted to the Authority Having Jurisdiction (AHJ). By applying a fire risk analysis to guide the designing phase, overall
fire safety of a wall assembly can be achieved more systematically as conducting FRA allows designers to clearly identify
elements that are more vulnerable to fire and simply replace them with other practical options. Severity of fire risk is
determined by considering the fire hazards of a wall assembly such as the exterior layer, insulation, vertical connectivity,
and external ignition sources (e.g., photovoltaic panels). Frequency of fire risk is assessed based on the factors affecting
fire likelihood, which are air cavity and fire-stopping applied in the design, and random design changes occurring during
on-site construction. Fire risk matrix is proposed based on these fire risk factors and efforts to reduce the fire risk level
associated with the wall assembly are given by systematically assessing the fire risk factors identified from fire risk analysis.
Current study demonstrates how fire risk analysis can be applied to develop fire-safe walls by reducing the relevant fire
risks? both severity and frequency.
