摘要： PROBLEM TO BE SOLVED: To provide a foundation pile followable to large deformation, and holding the support function of a structure in an earthquake and after the earthquake without fracture even to the large bending moment, shearing force and a turning angle thereby caused in a pile body generated in a stratum boundary and the vicinity of a pile head.
SOLUTION: This foundation pile is formed by connecting existing piles. Maximum bending yield strength is equal to or less than an existing pile general part under working axial force. A highly tough member 2 having curvature at maximum bending yield strength generating time larger than the existing pile general part is arranged in an underground part or a pile head part. For example, when using a steel pipe pile as the foundation pile 1, a steel pipe having an outer diameter smaller than the general part 1a of the foundation pile 1 is installed in the underground part or the pile head part of the foundation pile 1 as the highly tough member 2.

摘要： PROBLEM TO BE SOLVED: To provide a base isolation foundation structure of a structural body capable of effectively using an existing pile.
SOLUTION: In a foundation beam 4, pile heads of a plurality of existing piles 2 are connected to pile heads of new piles 3. A new structural body 1 is constructed on the upper part thereof. A sliding device 5 is formed on the upper face and connected to the foundation beam 4 through the sliding device 5. The new pile 3 is rigidly connected to the foundation beam 4, but the sectional diameter is set small by a design in which a vertical support force is taken into consideration. Since the bending rigidity is made small by making the sectional diameter small, when a horizontal force larger than a specified force acts on the new pile 3 from the foundation beam 4 by an earthquake or the like, a deflection occurs at the pile head of the new pile 3. Thereby, the pile head displacement becomes large but the sectional area becomes small and the section of the foundation beam 4 can be greatly reduced.
