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, two different
longitudinal ribs having trapezoidal and triangular cross-sections are modeled
and the stresses for the ribs are evaluated due to tire loading using finite
element analysis (FEA). Both of the longitudinal ribs are used for long span
steel bridges. The aim of this study is to compare the shape of the
cross-sections of the ribs under tire loading using FEA method.
