Cyclic Behavior of Reinforced Concrete Haunched Beams Failing in Shear
Abstract eng: This paper presents the research results about the testing of ten prototype reinforced concrete haunched beams subjected to cyclic loading. Beams were designed to present shear failure. Two groups of beams were tested: a) beams without shear reinforcement, and b) beams with minimum shear reinforcement. The cyclic testing allowed to fully validating a previous proposed equation to estimate the shear strength of reinforced concrete haunched beams. From the obtained results, it can be observed that haunched beams have a different shear behavior with respect to prismatic beams, having higher deformation and energy dissipation capacities, among other reasons, because nonprismatic beams exhibit an arching action along the haunched length as the main resisting mechanism, that favors smoother cracking patterns.
