Abstract:
The paper describes tests carried out on large scale reinforced concrete test units with details modeling those encountered in sections of Los Angeles' I-10 Santa Monica Viaduct. Lap-splices of column longitudinal reinforcement, and joint details including inadequate development of column reinforcement in the cap beam, and a total absence of special joint reinforcement would be considered unacceptable in new designs. The purpose of the tests was to obtain verification of analytical predictions that, despite the poor detailing the bents, could be expected to survive the design level earthquake without collapse. Test results confirmed that the lap splices should perform adequately under seismic attack, and the column/cap beam connections would maintain gravity load capacity after joint degradation
