PROBLEM TO BE SOLVED: To provide a joining structure between a pile and footing that can prevent a pile body and the footing from being damaged when a large bending moment is applied, while preventing rise of cost by using the footing of RC structure.SOLUTION: In a joining structure between a pile 1 and footing 3, the footing 3 is made of RC structure. The pile 1 is disposed so that an upper end surface 1u becomes lower than a lower surface 3l of the footing 3, and a pile head reinforcing part 7 of the RC structure joined to the footing 3 is formed integrally in a pile head 1a. The pile head reinforcing part 7 has a shaft reinforcement 13 fixing to the footing 3 and shear reinforcement 14 extending horizontally. A flexural capacity of a portion between an upper end surface 1u of the pile 1 in the pile head reinforcing part 7 and the lower surface 3l of the footing 3 is set lower than the flexural capacity of the footing 3 and the flexural capacity of the pile 1, and thereby a basic connection part 7a between the pile 1 and the footing 3 may be damaged in the ultimate state. |
