Improvement In Fatigue Properties Of Welded Joints Using Crack Initiation Resistant Steel Part2:Fatigue Crack Initiation Life Of Rib-To-Deck Welded Joints Of Orthotropic Steel Bridge Decks
Year: 2025
Type: article
Abstract: Fatigue durability is one of the problems in the maintenance of bridges. One of the areas of concern for fatigue crack initiation, the weld between the U-shaped rib and the deck of Orthotropic Steel Decks is known. The fatigue crack initiation life of a rib - to - deck welded joints was investigated using a developed steel with high crack initiation resistance. As a result, when the developed steel was used for the deck, the crack initiation life was prolonged by about 1.5 times compared with the case where the conventional steel was applied.
