Fatigue Life Evaluation of Welded Joints in OSD for Railway Bridges Considering Welding Residual Stress

AbstractAn orthotropic steel deck (OSD) has a complicated structure, and its fatigue life is mainly determined by various welding details. Fatigue assessment of deck-to-rib welded joints under long-term train loads is an important concern for engineers. Using the stress range–number of cycles (S-N)...
