Abstract:
Firstly,the paper analysed the temperature-field of a reinforced concrete beam after fire by the ABAQUS Finite Element Software,and proved its reasonable by comparing with the experiment results,then further analysed the mechanical properties changes of the reinforced concrete beam after fire,the conclusion can provide a reference for reinforcement of the reinforced concrete structure after fire.
