A new type of steel bridge deck with semi-open longitudinal ribs was designed to improve fatigue performance. By using full penetration welding and adjusting structural parameters, the new deck reduces stress concentration at critical points, enhancing its durability. The new design increases stress on the deck but improves welding quality and reduces stress concentration, making it more resistant to fatigue.
