In order to apply the mechanical deck joint to the prefabricated steel gird composite decks, shear resistance of the joint composed of concrete shear key and high-tension bolt was evaluated by the push-out test experimentally and analytically. In this study, shear resistance of the joint installed in the deck is evaluated by design equation. In comparison with resistances estimated by design equation and test results, the deck joint is structurally safe enough, and in the case of pointed loading efficient width of the prefabricated steel grid composite deck is about 1m long.
