Fatigue life prediction of stud shear connectors under corrosion-fatigue coupling effect
https://orcid.org/http://orcid.org/0000-0002-3543-4189
Based on the three-stage fatigue crack growth model, a corrosion fatigue life prediction method considering the coupling effect of corrosion and fatigue is proposed in this paper. In this case, stress factor amplitude was claimed considering the coupling effect of corrosion and fatigue. Three push-out tests in corrosion conditions were conducted to study the failure mode of studs. The crack propagation of studs, obtained through the push-out tests, was simulated in FRANC 3D to establish a library of adequate stress factor amplitude. According to the corrosion degree of the specimens, the corrosion dissolution rate formula was formed, and the corrosion fatigue life of the specimen was predicted. Results show that the error between the predicted and experimental values is approximately 25%.
