NFEA Modeling of RC Beams Having Exposed Longitudinal Reinforcement: Effects of Debonding on Shear Behavior

This study also presents a consistent beam-column element that provides a description of shear response. The element formulation is derived based on a two-dimensional micro-plane approach, where the material state of stress is defined by a two-dimensional state of strain. The advantages of the proposed model over other methods are demonstrated such as in predicting the change in shear stiffness. Unlike with other micro-plane models, the proposed model utilizes equilibrium to determine the sectional shear stress distributions that become irregular after cracking and due to other strength degradation effects. This approach enabled the proposal model to provide a more complete description of the shear stress distribution over the depth of the cross section over the entire loading history. Validation of this method is made against experimental test data of shear critical reinforced concrete beams both with and without shear reinforcement.
