Sectional forces on piles during earthquakes are affected not only by the inertial force of the structure but also by ground deformation. In this study, a series of shaking table and static lateral loading tests on pile groups and piled raft foundations were conducted in a centrifuge to estimate the influence of ground deformation on the bending moment in the piles. The results, including the effect of the ground deformation, were compared to those of the static lateral loading tests without ground deformation. Most of the inertial force was transferred to the subsoil through the raft by friction on the piled raft and the bending moments in the piles in the piled raft caused by ground deformation were almost the same as those in the pile group.
