Prediction of Shear Strength in RC Slender Beams

철근콘크리트 보의 전단강도 예측

This paper deals with the verification of the new truss model that has been conceptually derived and formulated in preceding research. Since the model includes the arch $coefficient-\alpha$, the characteristics of this coefficient are examined, and it appears that the $coefficient-\alpha$ is a function of a/d, $\rho$ and $\rho_v$. The arch $coefficient-\alpha$ is applied to the test specimens available in literatures, and the predicted values are shown to be in excellent agreement with the experimental results.
