Lapped Splices in High-Strength Concrete Flexural Members

고강도 콘크리트 휨 부재의 철근 겹이음에 대한 연구

An experimental study was conducted to evaluate the bond performance of reinforcing bars embedded in high-strength concrete. Ten beam spice Specimens using concrete with compressive strength of 240kg/$\textrm{cm}^2$ and 640kg/$\textrm{cm}^2$ were tested. The effect of several variables on basic development length is discussed. The test results showed that the current trend in concrete specification of making the splice length longer to compensate for having smaller cover and spacing may not be an effective approach.
