The present study evaluates the stress of deck and base shear of the isolated curved bridges, in seismic areas by considering the effect of soil-structure interaction. In order to Seismic Isolating of the bridge, double concave friction pendulum bearing are located between the middle columns and supports. The bridge is a three-span curved bridge with concrete box beams on bottom layers of non-cohesive soils with a high depth. Three-dimensional modeling and analysis was performed using ABAQUS software. The created model was non-linear analyzed by the Northridge earthquake. Comparing the results with the results of similar curved bridge with no Seismic isolator indicate that, isolated bridge deck stress and base shear has declined significantly. Therefore seismic isolation systems can improve of performance of structure and prevent damages during earthquakes.
