Proposed AASHTO Seismic Specifications for ABC Column Connections
Accelerated bridge construction (ABC) utilizes rigorous planning, new technologies, and
improved methods to expedite construction. Prefabricated columns and their connections
to adjoining bridge members (cap beams, footings, pile caps, and pile shafts) are the most
critical components of ABC in moderate- and high-seismic regions.
The TRB National Cooperative Highway Research Program's
NCHRP Research Report 935: Proposed AASHTO Seismic Specifications for ABC Column Connections
develops AASHTO specifications
for three types of precast column connections to facilitate ABC implementation in
moderate- and high-seismic regions.
