f wy) as well as their interactive influence (pwfwy). Thus, it is reasonably expected that high-strength steel bars can greatly reduce the necessary amount of shear-reinforcing bars. On the other hand, although the bond strength is influenced by the amount of shear reinforcing bars, it is not affected by the yield strength. Thus, there is often an issue that bond failure occurs before shear failure depending on the arrangement of shear reinforcing bars. It is a common practice to set sub-ties for the transverse confinement of the main re-bars as a method to prevent the bond
failure. However, it can also become a factor in decreased work efficiency due to the complexity of the construction.
This study experimented with simultaneous use of high-strength transverse reinforcing bars (f wy=800㎫) and U-shaped transverse reinforcing bars of regular strength (f wy=300㎫) in an attempt to decrease the necessary quantity of shear reinforcing bars. The effect of this attempt was investigated through fundamental experimental research in terms of the improvement in shear resistance and bond strength as well as the ease of construction.
