Abstract

Seismic isolators have been used to protect buildings, bridges and mission-critical
infrastructure from the damaging effects of earthquake shaking. In past earthquakes, most of the damages of
the bridges occurred due to the failure of the bearings and substructure. 3 models are going to use in this
Project. One is non-isolated bridge modal and two models of base isolated bridges with different elastomeric
bearings. Elastic time-history analyses were carried out using comprehensive finite element structural
analysis software package SAP2000.Time history analysis was conducted for the Bhujj Earthquake. Isolators
are to be designed by considering suitable soil type and site conditions.
The properties of isolators are to be introduced between super structure and sub structure. Influence
of the base isolator is to be studied. The influence of the elastomeric bearing in the dynamic behavior of the
bridge shows an extended time period, increase in deck displacement and decrease in base shear in both
isolated bridge models.
