FIU Electronic Theses and Dissertations
Slab beam superstructures have been used for short-span bridges since prestressed concrete began to be used in the US. Poor joint performance of these superstructures led to recent revisions to design standards; one example being the Florida Slab Beam (FSB). The FSB and other similar slab beam systems include a composite cast-in-place (CIP) reinforced concrete deck and joint between adjacent beams. An optimized joint design has been developed to accelerate the construction times and eliminate the need for a CIP deck by using ultra-high performance concrete (UHPC) in the longitudinal closure pour to connect the precast members.
The optimized joint …
