Behavior and Design of Precast Bridge Cap Beams with Pocket Connections

In conventional reinforced concrete bridge construction, cap beams and their connection to columns are designed to be capacity protected under strong earthquakes. This is because cap beams and connections are difficult to repair. The same design philosophy is mandatory for precast cap beams that are used in accelerated bridge construction (ABC), particularly in moderate and high seismic zones. ABC relies heavily on prefabricated reinforced concrete members. The National Cooperative Highway Research Program (NCHRP) report 698 provided a synthesis of different promising ABC connections. Pocket connections were identified as practical means of joining prefabricated columns and pier caps. The American Association of State Highway and Transportation Officials (AASHTO) Scan 11-02 revealed more recent studies about seismic performance of pocket connections.
