Seismic behavior of isolated bridges: A-state-of-the-art review

Abstract

An update state-of-the-art review of the behaviour of isolated bridges to seismic excitation is presented. The review includes the literature on theoretical aspects of seismic isolation, parametric behaviour of base-isolated bridges and experimental studies to verify some of the theoretical findings. A brief review of the earlier and current base isolation devices, proposed or implemented, is given, and aspects for future research in the area of isolation of bridges are included.
