Soil-structure interaction effect on the analysis of continuous bridge provided with rubber bearings and subjected to earthquake ground acceleration is studied. The rubber bearing is provided between the piers and deck slab and also between abutments and deck slab. The finite element method is used to model both the bridge structure and the soil. A beam element is used to model the continuous bridge, whereas a four-noded plane strain element is used to model the soil. The response parameters considered for the study are the base shear and relative displacement between pier and deck slab. It is concluded from the study that soil-structure-interaction has considerable influence on the behaviour of the isolated bridge structure and considering the soil-structure- interaction effect is either beneficial or detrimental to the bridge structure.
