Summary While several road bridges were damaged by the tanker fire, generally, fire protection measures are not considered in road bridge designs. In order to investigate the necessity of standardization for fire resistance performance of bridges, Examples of fire protection measures for road bridges are collected, and the repair cost with fire protection measures and their costs without the measures are estimated and compared with one another. In addition, a sampler of painted steel members damaged by fire to estimate peak temperature of the steel members at the time of fire was produced.
