Abstract
The authors evaluate the composite behavior of a bridge section consisting of a full-depth concrete slab that is connected by threaded steel bolts to an AASHTO-type concrete I-girder. The research conducts 13 push-out tests on specimens having shear pockets in the slabs to show both horizontal shear strength capacity and the behavior that threaded steel bolts exhibit when used as shear connectors to achieve composite action between the precast concrete panels and precast concrete girders. The specimens, cast and tested under static loading conditions, are used to determine the ultimate strength and failure mode of the shear connection system. Steel bolt length, along with their number, configuration in the shear pocket, and spacing are also examined. Results show that threaded steel bolts allow for full composite action between the precast concrete panels and precast concrete girders. The authors also note that their results, when applied to the load and resistance factor design guidelines of the American Association of State Highway and Transportation Officials, point to the Association's conservative estimate of design strength.
