| PCI Journal 80 Accelerated bridge construction incorporates innovative techniques and materials to efficiently reduce construction time and traffic disruption. It also improves work-zone safety for workers and commuters. Prefabrication of bridge structural components is a highly effective technique and is one of the accelerated bridge construction methods promoted by the Federal Highway Administration under the category of prefabricated bridge elements and systems. Several bridges have been built or rehabilitated using accelerated bridge construction methods. Examples in Utah include the Interstate 15 (I-15) Core Provo Center Street interchange, the Riverdale Road over Interstate 84 (I-84) bridge, and the I-15 South Layton interchange. Precast concrete deck panels, substructures, and superstructures have been frequently used in accelerated bridge construction. Connections between such reinforced precast concrete elements are among the most critical components of the structure. Researchers are investigating the adequacy of various connection configurations, especially in moderate to high seismic regions. These connections not only have to conform to accelerated bridge construction standards in terms of construction delivery time but must also resist earthquake-induced deformations and stresses. Lateral load capacity, displacement ductility, and reparability are three significant criteria for any connection considered in seismic regions. In this paper, a column–to–cap beam joint is investigated using ■ Although grouted splice sleeve connectors facilitate the construction of precast concrete bridges and accelerate construction, seismic bridge design codes prohibit their use in column plastic hinges.
