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.

Book Description
Pt. 1: The opportunity for the field testing of an isolated viaduct arose out of the demolition and reconstruction of the I-680/R-24 interchange in Walnut Creek, California. The southern section of the temporary separator bridge is seismically isolated, and this portion was the subject of a three-phase field study. This viaduct is the first new bridge in California to be seismically isolated. The primary objective of this investigation was to collect field data for the determination of the dynamic properties (mode shapes, modal frequencies, and damping ratios) of the viaduct, to assess the contribution of different structural components to the overall flexibility and damping characteristics of the structure, and to conduct analytical studies to verify the experimentally computed dynamic properties.
