PROBLEM TO BE SOLVED: To secure a fixed length of a beam main reinforcement in a thick beam in a short span without using a joint. SOLUTION: The size of a beam 3 is determined for instance, approximately L/D=200/100, to be a thick beam of a short span. Bent bars 7-10 are arranged in the direction of intersecting with a column main reinforcement in columns 1, 2, extend along through reinforcements 5, 6 from one end welded on the column main reinforcement or joined by a bundling wire or the like, and bent toward the inside of the beam 3 at a bending position P near the position of the deflection point of the moment of a bending moment M.
