This study deals with a flow to assess the seismic endurance capability of the existing building- foundation system enhanced with rehabilitation measures. In the proposed flow, first, the rehabilitation is carried out for the superstructure to satisfy the seismic endurance capability. Next, the examination of the rehabilitation of the foundation in the clarified building is carried out, because the building may have a possibility of collapse due to the poor bearing capacity or the endurance strength of piles due to a major earthquake. Two types of the retrofitted foundation are analytically investigated according to the flow: existing piles reinforced with additional piles, or an isolation system installed between the foundation and the pile top. The result shows that both measures are very effective to protect the piles from the inertial force and in-ground displacements.
