 Summary:
 This paper presents the basic principles seismic isolation of concrete bridgesusing different types connections between superstructure and substructure of construction.In the particular case of the bridge over river Dičina on the section Takovo – Preljina ofhighway E-763 Belgrade - Požega modeled cases with rigid and hinge connection, andcase with elastomeric bearings. Analised influence of the type connection on improvingseismic isolation of construction as well as the impact changes the stiffness of elastomericbearings on the resulting seismic forces. In the conclusions were presented basicobservations conducted analysis could be applied at the calculation similar bridges of thistype in seismic active areas.
