Fatigue life prediction of stud shear connectors under corrosion-fatigue coupling effect

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