Abstract:

Grouted Splice Sleeve (GSS) connectors are being considered for connecting bridge columns, footings, and pier caps in Accelerated Bridge Construction (ABC). A repair technique for precast reinforced concrete bridge column-to-footing and column-to-pier cap joints constructed with GSS connectors has been developed. The repair utilizes prefabricated carbon fiber-reinforced polymer (CFRP) shells, epoxy anchored headed mild steel rebar, and non-shrink concrete to relocate the column plastic hinge. Prior to the repair, undamaged column-to-footing and column-to-pier cap joints constructed with GSS connectors were tested to failure under a quasi-static cyclic lateral load. The as-built column plastic hinge region was subsequently repaired, and the repaired joints were tested following the same cyclic loading protocol as the as-built specimens. The plastic hinge was successfully relocated to the column section adjacent to the repair. The repair method is simple and rapid and could be used to repair bridges constructed with joints utilizing GSS connectors. The method is general and it shows promise for retrofitting or repairing bridges constructed with conventional cast-in-place joints as well.
