description PURPOSE:To obtain a sufficient flexural strength by forming a concrete reinforcig bar, bent at one or more point and made of FRPs (fiber-reinforced plastics), and bending the concrete reinforcing bar according to the sectional shape of a concrete structure. CONSTITUTION:A concrete reinforcing bar 1 having sections bent at one or more points and made of FRPs is formed in a flat shape while t/w=2.8 holds in the relationship of a bend radius R on the inside of a bending section and thickness (t). When the directions of bending of adjacent bending sections are equalized, L>=3.5XRXtheta+3.5XR'Xtheta' holds in relationship with length L between the adjacent bending sections when the bend radius on the inside and the angle of bending are represented by R, theta and R', theta'. Accordingly, a sufficient flexural strength can be acquired even when a sectional area is large and a curvature radius is large.
