| Abstract: | In view of fire damage to the cable of a bridge,the finite element model is established based on random model of steel strand with fie damage.The service behaviors of the bridge before and after cable fire and before and after the stayed-cable is changed are compared,which may provide theory reference for the replacement of cable. |
