1-9. (canceled)
A rebar structure comprising:
- a plurality of longitudinal bars extending in an axial direction;
- a plurality of shear reinforcing bars arranged to surround the longitudinal bars in a rectangular form in a plane intersecting the axial direction of the longitudinal bars;
- and
- a plurality of bond reinforcing bars arranged adjacent to the shear reinforcing bars in the axial direction of the longitudinal bars,
- wherein the longitudinal bars comprises a first longitudinal bar, a second longitudinal bar, a third longitudinal bar and a fourth longitudinal bar that are arranged clockwise at least at four corners of the shear reinforcing bars, a fifth longitudinal bar provided between the first longitudinal bar and the second longitudinal bar and adjacent to the first longitudinal bar, a sixth longitudinal bar provided between the first longitudinal bar and the second longitudinal bar and adjacent to the second longitudinal bar, a seventh longitudinal bar provided between the third longitudinal bar and the fourth longitudinal bar and adjacent to the third longitudinal bar, and an eighth longitudinal bar provided between the third longitudinal bar and the fourth longitudinal bar and adjacent to the fourth longitudinal bar, and
- wherein the bond reinforcing bars comprise a first bond reinforcing bar provided around at least the first longitudinal bar and the fourth longitudinal bar and having an inner periphery facing the fifth longitudinal bar and the eighth longitudinal bar.
