    • PROBLEM TO BE SOLVED: To provide a reinforcement method of piled piers capable of improving both yield strength of piled piers and deformation performance of piled piers and improving earthquake-resisting performance and to provide a reinforcement structure and a piled pier.
      SOLUTION: In the reinforcement method of piled piers, brace members 13 are provided between piles 11 and upper materials 12. Damper members 14 are provided between the brace members 13 and the upper materials 12, between the brace members 13 and the piles 11, or both. The damper members 14 are made to yield to a first-stage earthquake having a prescribed magnitude, and the brace members 13 are made to yield to a second-stage earthquake larger than the first-stage earthquake.
