Recently, there is a situation that the high strength shear reinforcement might be used to shear reinforcement of reinforced concrete construction building. To the beam in these buildings the hole of penetration through the beam is often installed. Then, the open hole reinforcing bar of the high strength of the 1275N/mm^2 class in the yield stress degree is used. It is thought that it is made light, prevent overcrowded bar arrangement, and the reliability of structure improve by using the opening reinforcement sources made from one reinforcement. However, concrete intensity and shear reinforcement strength and a continuation the opening spacing is not yet considered fully. This research experiments to understand the effect of reinforcement of opening reinforcement which uses the high strength reinforcement of 1275N/mm^2 for RC perforated beam where the shear fracture is caused. Destructiveness, ultimate shearing strength and adaptability of expression in the past are examined. In addition, it designs new type of opening reinforcement.
