This paper proposes a numerical simulation analysis of the problems in a bridge after a fire. The problems were discussed to provide safety for the bridgework domain. The article used a fire dynamic simulation (FDS) software for analysis. The investigation on the scene of a bridge fire and the detection of bridge damage caused by fire were described to discuss the effects on concrete and steel girder components. The effects of fire temperature and smoke at the scene of a fire were estimated to provide criteria for bridge fire prevention and in enhancing bridge safety. This paper proposes using a sprinkler system to protect bridges against fire hazards and found out the reasonable flow rate to implement protection with a minimum water quantity. For the characteristics of concrete fire damage, a fire-damaged reinforced concrete bridge inspection and evaluation method was introduced using an engineering example, and a bridge fire handling scheme was proposed. The method and idea could provide beneficial references for handling similarly inclined bridge fires. A risk management evaluation method was planned and a numerical simulation model of a bridge fire was built to provide criteria for improving bridge management safety.
