The Interstate I5/I605 Separator in Los Angeles County was severely damaged during the October, 1 1987 Whittier Narrows Earthquake. This damage included non-ductile shear failure in the reinforced concrete columns of a multiple column bent. The observed damaged and nearby recorded ground motions provided an excellent opportunity to assess the ability of analytical models to predict the seismic response of non-ductile reinforced concrete bridges and the worthiness of repair and retrofitting measures.
