Seismic Evaluation of a 30-Year Old Non-Ductile Highway Bridge Pier and Its Retrofit
MetadataShow full item record
This report presents an experimental investigation of the seismic behavior of a full-scale prototype highway bridge cap beam-to-column subassemblage and its retrofit. Retrofitting consisted of strengthening the joint core and cap beam by providing a high strength concrete jacket and longitudinal prestress. Following extensive experimental testing, the ATC 6-2 evaluation method and the evaluation method recommended by Priestley et al, (1992) were analyzed to determine their compatibility with the experimental results. A proposed energy-based evaluation methodology is introduced to overcome shortcomings in the current evaluation methods.
