Steel bridges with orthotropic decks are facing fatigue issues due to cracks. Researchers used computer models to analyze different shapes of floor-beam web cutouts to improve fatigue resistance. The study found that choosing the right cutout shape based on actual load and structural conditions can help design and strengthen steel bridge decks.
