[CS3-02] Analytical study on the Effects of angle reinforcement on fatigue strengths of U-rib and transverse rib connections.
Keywords:Orthotropic steel deck, Fitigue, Reinforcement, Finite element analysis
Orthotropic steel decks (OSDs) are widely used for long bridges due to its light weight. Furthermore, it could be used for replacement of RC/PC slabs because of short construction time and small seismic load. However, the OSDs have low fatigue strengths. Thus, a study project has been started to improve fatigue strengths of U-rib and transverse rib connections of OSDs. In this paper, angle reinforcement is evaluated by FEA with an actual bridge model. As a result, the angle reinforcement is effective to improve fatigue strengths of the connections because it can reduce the maximum principal stresses and stresses perpendicular to weld bead.
