Evaluation of the crack model of V type longitudinal ribs on orthotropic deck using finite element analysis

الملخص EN

The long span orthotropic bridge decks applied around the world are used with open or closed cross-sectional longitudinal ribs placed below the steel deck to increase the strength of the deck.

fatigue cracks are developed in the longitudinal ribs due to traffic loadings.

in this study, v type of longitudinal rib cross-sections is modelled and the stresses for the rib are evaluated under tire load loading using finite element analysis.

longitudinal ribs are used for long span steel bridges.

the aim of this study is to compare the fatigue crack path of the longitudinal rib on a real bridge with the stress pattern in the finite element model.
