Abstract: This paper examines the possible uses and the advantages of seismic isolation at the base of girder bridges. The attention is focused in particular on the feasibility of adopting a system based on the abatement of the horizontal stiffness of foundation piles, as is obtained by using piles partly nonconfined by the surrounding soil. Eight bridges with standard characteristics, representing a sufficiently wide class of girder bridges, were selected. On these structures, subjected to real seismic excitation, a parametric analysis was conducted with the aim of evaluating the optimal characteristics of the isolation and the applicability of the technique
