| Abstract: | Take Waibaidu Bridge reconstruction in Shanghai as an example,by using axle load spectrum and Miner cumulative damage rules,the fatigue life of each detail is calculated. The fatigue life of steel deck system in the reform design is checked to find out whether or not it can meet the using function. Finally,design is opti- mized based on the calculating results. |

| Keywords: | old bridge reconstruction orthotropic steel deck fatigue life prediction design optimization |
