Evaluation and seismic retrofit of highway bridge substructures with tapered columns

摘要

The purpose of this study has been: (1) to evaluate the highway bridges on the I-80 in the Reno-Sparks area for their damage potential during string earthquakes; and (2) to determine Effective means of retrofitting the substructure components in these bridges. The first part of the study Was completed in the Fall of 1993, the result of which are presented in this paper. A data base Consisting of 26 bridges was formed. The focus of the study was on bridges with relatively thin, Tapered columns.
