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...
