This paper presents the final research results and interpretations about the testing of prototype reinforced concrete haunched beams subjected to cyclic loading. Beams were designed to present shear failure. Beams had no shear reinforcement. These haunched beams are identical in geometry and reinforcement to a set of haunched beams previously tested under static loading. These additional cyclic testing allowed to fully validate a proposed equation to estimate the shear strength of reinforced concrete haunched beams, taking into account parameters such as the haunch angle, the concrete compressive strength, the shear reinforcement and the negative contribution of the inclined longitudinal reinforcement. From the obtained results, it can be observed that haunched beams have a different cyclic shear behavior with respect to prismatic beams, having higher deformation and energy dissipation capacities, among other reasons, because non-prismatic beams favor an arching action in the haunched length as the main resisting mechanism.
