Abstract:
Shear strength of structural deep beams is important in design. This paper focuses on the shear strength of deep beams combined with anchorage failure, based on upper bound solutions in the theory of plasticity. The solutions showed that the shear strength combined with anchorage failure is lower than other shear strength due to web crushing in some range of design parameters. This study investigates the effects of shear span ratio, ratio of embedment length of bars beyond support to beam depth, and vertical reinforcement ratio on the failure modes and strengths. An experiment was performed to compare with the plastic solutions and showed good agreement with those of theoretical results. Finally, this paper proposes a range of design parameters for ductile failure mode of reinforced concrete deep beams, which ensures a safe detailing of end anchorage for the flexural failure of deep beams.
