- Abstract:
- The main span steel box girder of Jiu-jiang highway bridge over Yangtze river is studied in this pa-per.Through finite element analysis on the real bridge structure,the fatigue specimen which can reflect stressstate of rib-to-reck welded joints of orthotropic steel bridge deck is made.Based on the theoretical analysis andstatic load test; the corresponding relationship of the load and stress of research part is gotten. The fatigue fail-ure form of the structure detail,stress -life curve and allowable stress amplitude are obtained by the fatiguetest. The result can be used for the evaluation of fatigue life，health detection and maintenance and repair ofthe bridge,which can also be used as reference for the design of other bridges.
