A parametric analysis of typical base isolated bridges was
conducted. The bridges were located in different soil types and
were subjected to different earthquakes. The work had two main
objectives: to asses the effects of the nonlinear behavior of the
isolation pads of the bridges on the seismic responses
(accelerations, displacements, and pier seismic forces), and to
study combined effects of base isolation and inertial interaction
due to the presence of flexible foundations. The analytical models
used for the study were selected on the basis of initial evaluation
of different models proposed in the literature to represent a
bridge structure and to evaluate the isolation pads' nonlinear
behavior. The results of the work show the efficiency of base
isolation pads in improving the seismic performance of bridges in
most cases. They suggest that the inertial SSI effects will not be
generally important for bridge foundations designed with a factor
of safety of 3, with more than one line of piles in either
direction, but for slender piers it is important to carefully
evaluate the translations on top of the piers due to the rocking
effects of the foundation.
