In this study, we conducted a bending test of RC beam member reinforced by this method aiming to verify the bending behavior of the reinforced part when a high bending compressive stress was applied. As a result, when a high bending compressive stress of 100 N/mm² or more was applied to the reinforced part, the part was undamaged. And it can be said that the bending crack position can be controlled by the crack induced joint since bending cracks did not occur at any places other than the crack induced joint.
