Abstract
The experimental program included testing of four types of specimens. The first type represents column-to-foundation connections using 1/6-scale replicas of the hinges in piers 2 and 3 of the Rose Creek Bridge. Five specimens of this type were tested. The purpose of the first four sprcimens was to determine the influence of reinforcement details in the hinge region on energy absorption capacities under cyclic loads. The fifth specimen was used in a pilot study to determine the cyclic response of hinged columns with inadequate steel development length, and to develop and test a repair method for damaged columns.
