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
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.
