Abstract:
A mechanical approach for the inelastic flexural analysis of reinforced concrete bridge piers, presented in a companion paper, is applied and the results are compared to the experimental measurements from two large-scale tests. The details of the practical application are discussed and, based on the reference behavior from the experiments, the capabilities and limitations of the method are investigated. The approach uses discontinuous stress fields to account for the influence of shear on the flexural behavior and combines it with the tension chord model to include the bond-related interaction between concrete and reinforcement. Both the global and the local load-deformation behaviors are analyzed in the elastic and inelastic range, providing a complete description of the flexural response along the backbone of a cyclic load history.
