Abstract
In this study, the coupled shear‐bending behavior of reinforced concrete (RC) beams was investigated. In an experimental study, 12 RC specimens were tested under close to constant shear span‐depth ratios but with variable flexural and shear reinforcement ratios. The primary focus was to analyze the effect of the inclination of the failure section and of the aggregate interlock on the shear‐bending resistance. Propagation of characteristic crack pattern, the shape, and the behavior of the failure section as well as the relative movements of the failure crack faces were studied. One conventional specimen and 11 special members, where aggregate interlock was eliminated along the web in the failure crack, were tested.
