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.
