Fire risks may be underestimated when ASET and RSET are individually derived and compared in the performance-baseddesign of a building. Accordingly, the need for the real-time coupling of fire and evacuation simulations has emerged.
Therefore, in this study, the predictive performance of CFAST, which requires relatively low computational cost andexpertise, was verified as an alternative to FDS, which has limitations in coupling with evacuation simulation because ofits high computational cost and expertise. Specifically, the prediction performance of the heat and smoke diffusion behaviorwas verified by comparing the CFAST prediction results according to the division method of the corridor connected to thefire room with the FDS. The results confirmed that CFAST yielded appropriate results within the model uncertainty rangeof the FDS for the upper-floor temperature and smoke detector operation time when the corridor was divided into intervalsequal to the width. Simultaneously, owing to the limitations of the numerical model for the flow velocity of the ceilingjet, it was confirmed that considerable attention is required to predict the operation time of the heat detector using CFAST.
