BRIDGE ABUTMENTS: ASSESSING THEIR INFLUENCE ON EARTHQUAKE RESPONSE OF MELOLAND ROAD OVERPASS

This paper (the second of a 2-part sequence), which describes a program of research on the seismic response of bridges and bridge abutment systems, examines the suitability of abutments models (described in the first paper) by comparison of model predictions with dynamic response parameters identified from strong-motion earthquake records obtained on the Meloland Road Overpass (MRO) during the 1979 Imperial Valley earthquake. This study focuses on the influence of the abutment models and tries to verify their applicability using the strong-motion data. The time-window analysis of the response of the MRO abutments and superstructure highlighted the contrast between the earthquake response of the embankment soil and the bridge deck. The details of the study are described, and the study findings are discussed.
