Fatigue Behaviour of Closed Stiffener to Crossbeam Connections in Orthotropic Steel Bridge Decks

This study concerns the behaviour of the closed stiffener (trough) to crossbeam connection in orthotropic steel bridge decks and in particular, the connection where a continuous closed stiffener passes through the crossbeam. For this connection, the crossbeam in-plane and out-of-plane behaviour is analysed. The nominal stresses for unit loads on...

Fatigue classification of welded joints in orthotropic steel bridge decks

This dissertation presents the research into fatigue classifications of welded joints in orthotropic steel bridge decks. These classifications are needed to calculate the fatigue life of these joints and should be included in the design codes. For years bridge design was mainly based on static loading. Due to the development of modern light...
