| Abstract: | Fatigue is one of most important factors influencing the durability of steel bridges.It is essential for bridges managers to perform fatigue inspection and repair on steel bridges,which can make steel bridges in good situation.In order to facilitate decision making,the paper proposed a computing method of life-cycle cost for design schemes of fatigue inspection and repair on steel bridges based on life-cycle cost analysis(LCCA),and in which user cost and failure cost were taken into account.At the end a ste... |
