| Abstract: | The finite element modeling method is used to stimulate the course at which a reinforced concrete beam isn't loaded until it has fissures and the principle of residual life evaluation on the basis of elements of damaged beam is introduced.Based on ANSYS,the degree of damage and residual life after the reinforced concrete beam being split are calculated with engineering examples,which gives a reference to life evaluation of the bridges in service. |

| Keywords: | reinforced concrete beam finite element modeling degree of damage residual life evaluation |
