Experimental Study on the Root-Deck Fatigue Crack on Orthotropic Steel Decks
SSRN Electronic Journal, 2021 The root-deck crack is one of the most concerned fatigue issues on orthotropic steel decks (OSDs) as it is unfavorable for the serviceability of the bridge while being difficult to detect. In this paper, the fatigue test was designed and carried out by using beach marking method to record the crack propagation process.

DETERMINATION OF THE RIB-TO-CROSSBEAM STRESSES IN ORTHOTROPIC STEEL DECKS
Proceedings of International Structural Engineering and Construction, 2023 For long span bridges, the orthotropic steel deck (OSD) is the most popular option for the bridge deck. Normal OSDs consist out of the steel bridge deck, the longitudinal stiffeners (ribs), and the transversal beams. All of the elements are welded together.
