Evaluation of Bridge Decks as Lateral Bracing for Supporting Steel Stringers
A full-size test on a wooden bridge deck showed that the deck nailers and the connections between the nailers and planks were the main contributors to the lateral stiffness of the deck. Design methods are presented for the bracing requirements for steel stringers including the required coefficient of friction. Various typical bridge decks were evaluated, and it was found that the decks had sufficient stiffness to force the supporting stringers to yield before buckling. The required coefficient of friction for stringers with span-to-depth ratios = 40 is 0.08. Less friction is required for smaller span-to-depth ratios.
