PROBLEM TO BE SOLVED: To reduce a number of shear keys when using a PCaPC member, at the same time securing shear resistance performance at an edge of the member.SOLUTION: A joint structure is for a joint between a first concrete member and a second concrete member. The first concrete member is a precast pre-stressed concrete member that includes a main reinforcement, a tendon and member concrete. The tendon is a reinforcement disposed nearer on a central side of a cross-section of the precast pre-stressed concrete member than the main reinforcement, having a diameter larger than the main reinforcement. The main reinforcement and the tendon protrude from an edge surface of the member concrete in a member axial direction and are embedded in the second concrete member, and the length embedded in the second concrete member of the tendon is shorter than that of the main reinforcement.SELECTED DRAWING: Figure 1 |
