In a first embodiment, the structure 1 has a wall 2 made of concrete, with distributing bars 3 and fibrous fiber reinforced reinforcements 4 arranged therein as streak reinforcements. The force distributing reinforcements 3 are arranged on the outer surface side and the inner surface side of the wall 2 respectively along the horizontal direction (the depth direction of the paper surface) as an outer muscle and an inner muscle. The wall 2 is provided with streak reinforcing members such as other force distributing reinforcements and main reinforcements, but they are omitted.
The streak-like fiber reinforced reinforcing material 4 is used as a width stopping bar that connects the distributing bar 3 on the outer side and the distributing bar 3 on the inner side. The streak-like fiber reinforced reinforcing material 4 is arranged in a direction crossing the distributing muscle 3 .

The streak-fiber-reinforced reinforcing material 4 is formed in a rod shape by impregnating reinforcing fibers with a matrix resin, and the directionality of the reinforcing fibers is arranged in the longitudinal direction of the streak-fiber-reinforced reinforcing material 4 .
The reinforcing fibers of the streaky fiber reinforcing material 4 can be carbon fibers, glass fibers, aramid fibers, etc., but it is desirable to use basalt fibers, which are comprehensively superior from various points of view.
The matrix resin with which the reinforcing resin is impregnated may be either a thermoplastic resin or a thermosetting resin, but in this embodiment, an epoxy resin, which is a thermosetting resin, is used.

Both ends of the linear fiber reinforced reinforcing material 4 are divided along the longitudinal direction (fiber direction of the reinforcing fibers) to form two divided portions 5a and 5b, respectively. One divided portion 5a is provided with a curved portion 6a which is partially curved downward to form a U shape. The other divided portion 5b is provided with a curved portion 6b that is partially curved upward to form a U shape. The divided portions 5a and 5b provided with these curved portions 6a and 6b correspond to the curved divided portions of the present invention. Hereinafter, the divided portion provided with the curved portion may be referred to as a curved divided portion.

The streak-like fiber reinforced reinforcing material 4 is arranged along the thickness direction of the wall and is arranged so as to intersect the force distributor 3 .
