Ductility Design of Foundations of Highway Bridge Abutments.pdf
Taken from Abstract: Ductility design of foundations of abutments against severe earthquakes as been newly introduced in the Specifications for Highway Bridges in Japan. This paper describes the summary of the ductility design method as well as its background. One of the features of this method is the adoption of a new procedure to evaluate seismic active earth pressure that is applicable up to high seismic loads based on the modified Mononobe-Okabe method. We also conduct back-analyses of the case histories of abutments including foundations damaged in the past earthquakes following the ductility design method proposed here. The results from the back-analyses confirm the applicability of the ductility design method.
