Book Description
This report summarizes the principal findings of a four year study for Caltrans of the seismic response of older multi-level, multi-column reinforced concrete bridge structures. Methods have been devised to improve prediction of the global response of these structures, to analyze and assess their local behavior, and to retrofit them to achieve adequate seismic behavior. The behavior of these structures has been found to be complex and influenced by a wide variety of parameters. Moreover, existing analysis methods often provide non-conservative estimates of behavior. The investigations conducted provide greater insight into the response characteristics of existing multiple column bridge structures. These have permitted development of improved analytical models and tools, retrofit strategies and design concepts.
Seismic Assessment and Retrofit of Existing Multi-column Bent Bridges

Book Description
The main objective of this research was to assess the seismic vulnerability of typical pre-1975 WSDOT prestressed concrete multi-column bent bridges. Additional objectives included determining the influence of soil-structure-interaction on the bridge assessment and evaluating the effects of non-traditional retrofit schemes on the global response of the bridges. Overall this research highlighted the vulnerability of non-monolithic bridge decks and shear-dominating bridge columns in pre-1975 WSDOT prestressed concrete multi-column bent bridges as well as the importance of including soil-structure-interaction, calibrating the force/displacement characterization of the columns to experimental test data and detailed modeling of the bridges such as expansion joint/girder interaction. In the end, the seismic assessment of bridges is a cost/efficiency issue. Each bridge is different, therefore, investing in improved analyses up front will enable an efficient use of the limited funds for bridge improvement, resulting in a significant savings overall.
