Abstract |
This paper as Part II of the present study deals with the verification of the new truss model that has been conceptually derived and formulated in Part I. Since the model includes the arch coefficient-α, the characteristics of this coefficient are examined, and it appears that the coefficient-α is a function of a/d, ρ and ρ After transforming the model Into a sectional approach, the formula for predicting the stirrup stress, the longitudinal steel force, and ultimate shear strength are derived. Then, the equations are applied to the test specimens available in literatures, and the predicted values are shown to be in excellent agreement with the experimental results.
