The article introduces a new method to analyze the behavior of slab-decks in bridge construction. By refining a rotational spring model, the researchers were able to accurately predict the moment and tension in the slab-deck. They developed a detailed boundary model to assess crack depth and rebar stress, which can help in designing reinforcements for bridges. The new analysis model successfully predicts the cracking state of slab-decks, making it useful for bridge construction.
