Abstract

Structural responses recorded during three recent earthquakes (1992 Landers and Big Bear and 1994 Northridge) were used to evaluate the performance of the retrofitted single column viaduct (Route 101215 Interchange in Colton). The column deformation experienced range from low in the Northridge earthquake up to about 70% yield deformation level during the Landers earthquake. These results were compared with the deformation-based design practice for column retrofit. Effect of foundation contribution was also compared with the design practice. Results from this study support the successful performance of other similarly retrofitted bridges during the Northridge earthquake.
