This report describes a research project to investigate the dynamic responses of soil and a reinforced concrete pile subjected to seismic loading. The soil profile included a nonliquefiable crust overlying liquefiable layers, thus producing permanent lateral spreading displacement. The pile was subjected to the combined effects of inertial loads from the acceleration of the superstructure mass and kinematic loads from the nonliquefiable crust. Large pile strains were found to develop after liquefaction was triggered. However, the interaction of inertia and kinematics appears to be a site- and project-specific phenomena.
