At present, the performance for fire resistance of the bridges is not generally required in its design. However, many damaged examples by the fire due to the traffic accident under the bridge, doubt fire, incendiary fire and so on, have been reported. Therefore, the evaluation of the fire resistance for the bridges is becoming important. First, the evaluation method of the fire resistance for the the steel-concrete composite girder bridge is discussed. Next, in order to verify the validity of the heat transfer analysis, the analytical and test results of the heating test of the reinforced concrete srab are reported. Finaly, as the results of the numerical analysis, the distribution of the temperature and the ultimate strength of the composite girder are reported and discussed herein.
