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.
