Severe corrosion damage on the deck surface of a orthotropic bridge deck with bulb rib has been reported in Japan. Therefore, in this study, structural behaviors of a orthotropic bridge deck was numerically examined using FE analysis program MARCment2010. Thus, its deck thickness was decreased according to corrosion damage level of the deck. The deformations and the stress distributions of a orthotropic bridge deck with bulb rib were compared and evaluated.
