| Abstract: | The steel corrosion leads the concrete around it to damage.Using damage mechanics,this paper studied the damage evolution of the concrete structures caused by the steel corrosion.By defining the damage degree of concrete,the relation among the damage degree,corrosion current density and corrosion time-varying was established,which reflected the process of damage evolution. |

| Keywords: | Damage degree Corrosion current density Steel corrosion |
