Development of a fatigue experiment for the stiffener-to-deck plate connection in Orthotropic Steel Decks

Popis výsledku v původním jazyce

Orthotropic Steel Decks (OSDs) are widely used in long span steel bridges since they are extremely light weighted and very efficient for resisting localized traffic loads. As this type of bridge deck consists of a complex network of longitudinal and transverse stiffeners, it is very sensitive to fatigue. Moreover, there is a lack of understanding concerning the actual fatigue behaviour. Therefore, a small-scale fatigue test has been designed for which the stresses would correspond with actual OSDs. Taking into account the possibilities available in laboratory conditions, the stress distribution at the considered weld does not perfectly match when using only one longitudinal stiffener. Nevertheless, relevant test data was obtained showing the dominance of weld toe cracks. In addition, beach marks are added during the tests. As a result, more information became available about the crack propagation. This information is very helpful when using fatigue assessment tools such as fracture mechanics.
