Although the research of high strength materials is in process briskly in the inside and outside of the country, in south korea, the research of high strength materials is insufficiency.
Generally shear resistance of RC beam is influenced dominantly by amount of shear-reinforcing bars(p w ) and yied strength(f wy). Therefore, I come to the conclusion that if use shear reinforced bar with shear reinforced bar, it leads to decrease of the quantity of shear reinforced bar and effects on the security of shear-restraint force of member.
This study experimented with not only the mixture of high strength-reinforced bar and U-shaped reinforcement normal strength -reinforced bar devises efficient improvement, but also it incites improvement of bond capacity and carries out an experimental study for improvement of member resisting force, finally it evaluates bond capacity quantitatively on the lines of main reinforcement the restraint method.
