Corrosion accelerates the propagation of fatigue damage and significantly reduces the fatigue life of the orthotropic steel bridge deck (OSBD). This paper experimentally investigates the effects of local corrosion on the fatigue behavior of rib-to-deck (RD) joints in OSBDs. Firstly, an accelerated corrosion test was conducted to obtain corrosive effects for various corroded RD joint specimens. Next, the 3D scanning technology was used to test the geometric characteristics of corrosion regions. Then, the strain, failure mode, crack growth, and fatigue performance of corroded RD joints subjected...
