Abstract
This paper presents the development of new connection systems for composite action between steel girders and concrete decks to allow for rapid replacement of deteriorated concrete. The most common diameters of steel shear studs used in composite bridge construction are 19.1 mm and 22.2 mm with a height of generally 127 mm. The experimental program at the University of Nebraska has proven that the strength of the proposed 31.8 mm studs is about twice that of the 22.2 mm studs. This would allow for fewer studs along the length of the steel girder which would decrease the effort of the deck removal from around the studs, and the probability of damage to these large studs and to the girder top flange.
