Many examples of the bridge damaged due to accidental or incendiary fire heating up the steel bridge from below have been reported. When steel girder bridges are exposed to fire, it is important to estimate the temperature of each member. The surface temperature of steel member can be estimated by the damaged coat. Therefore, the gas and electric furnaces, the authors tested the various heating coat. Creating a sample of damaged coating in order to estimate the surface temperature, we have established a method for evaluation. In addition, we have applied to the removed bridges with the evaluation method.
