Assessment and Testing of Column Lap Splices for the Santa Monica Viaduct Retrofit

by M. J. Nigel Priestley, Univ of California, La Jolla, United States,
Frieder Seible, Univ of California, La Jolla, United States,



Document Type: Proceeding Paper

Part of: Structural Engineering in Natural Hazards Mitigation

Abstract:

This paper describes assessment and the full-scale test of a 3 ft. (914 mm) dia. column containing #11 (34.9 mm dia.) reinforcing steel lap-spliced in the critical region. The column modelled typical details of the Santa Monica Viaduct. Existing code equations predicted that inadequate development length was provided, but a 'first principles' approach indicated that satisfactory performance could be expected.
