An analytical formulation based on the truss analogy has been used for prediction of shear capacity in uncracked ‘push-off’ specimens made with natural concrete and with recycled aggregate concrete. The analytical model shows that shear capacity is a function of tie force across the shear plane. This tie force is reckoned to consist of the tensile capacity of concrete in the shear plane and the tensile force resisted by the clamping reinforcement bridging the shear plane. It is shown that if the ‘concrete contribution’ to this tie force can be estimated, then the amount of clamping reinforcement required to furnish the balance of the force in the tie can be determined for the condition of yielding of this reinforcement. The proposed methodology has been validated by comparing the predicted amounts of clamping reinforcement required to resist reported shear capacities in the literature with the provided values. Based on the shear friction theory, design for push-off shear capacity using strut-and-tie models has been proposed.
