Fire resistance performance of the SFT (Submerged Floating Tunnel) is important one of the various researches. If fire break out in SFT, it is damaged by thermal loads. The damage of the SFT varies by type of fire. Structure of the SFT is able to collapse partially by fire scale and fire exposure time. For this reason, fire resistance design of the SFT must be suggested. Fire resistance performance of SFT could be investigating for fire resistance design of SFT. Fire condition could be expressed fire curves which are suggested by fire scale and fire exposure time. In this paper, temperature distributions of the SFT were investigated through FE analysis under various fire scenarios. Heat transfer analysis was applied to investigate conduction of heat by fire. And there was to draw the biggest influence fire condition to the SFT from FE analysis results. Also, preliminary study was performed for fire resistance design.
