PROBLEM TO BE SOLVED: To provide a rebar structure in which a through-hole for equipment piping can easily be constructed in the vicinity of a column.SOLUTION: A main reinforcement 21 for a beam is constituted by including a normal rebar 212 with the yield point or 0.2% proof stress defined in JISG3112 and a high-strength bar 211 with the yield point or 0.2% proof stress larger than that of the normal rebar 212. The high-strength bar 211 is disposed in a beam-column connection 200, and a first high strength region 201 and a second high strength region 202 along the beam length direction from the beam-column connection 200, respectively. The normal rebar 212 is disposed in a normal rebar region 210 positioned in the side opposite to the beam-column connection 200 across the first high strength region 201. An opening region 50 arranged with a through-hole 5 for equipment piping is contained in the first high strength region 201 and the second high strength region 202. |
