Concrete Shear Failure in Reinforced-Concrete Elements
Publication: Journal of Structural Engineering
Volume 122, Issue 9
Abstract
Orthogonally reinforced panels subjected to in-plane shear and normal loads in certain cases fail by a mode called concrete shear failure, because of a considerable sliding which occurs between the faces of the ultimate critical crack. This mode is observed when the transverse reinforcement is considerably less than the longitudinal reinforcement. In this case failure occurs after yielding of the transverse reinforcement, but prior to yielding of the longitudinal reinforcement. An analytical study of this mode of failure is presented. It has been shown that the so-called concrete shear failure is in fact due to neither shear nor compression of concrete, but due to a tension caused by splitting of concrete. It is further shown that splitting results in a sliding of the ultimate critical crack faces. The theoretical results of this analysis are compared with existing experimental data on panels of reinforced concrete, which were tested under various shear and normal in-plane loads. The test panels were constructed of normal as well as high-strength concrete. For both qualities of concrete, the theoretical and experimental results are found to be in excellent agreement.
