Title: Resistance to Shear of Reinforced Concrete Beams
Author(s): J. Taub and A. M. Neville
Publication: Journal Proceedings
Appears on pages(s): 715-730
Abstract:It is shown that hooks at the ends of plain round bars materially increase1 the load-carrying capacity of a beam failing in shear-tension. Means of lessening the destructive action of hooks are indicated. Beams with deformed bars and vertical stirrups show a considerable resistance to slip, so that composite action in. the end parts of the beam is well preserved. This is not necessarily so when no stirrups are present as in some cases the wedging action of the deformations may tend to split the concrete. Bond failure is shown not to be a primary cause of failure but merely a consequence of the redistribution of internal forces following the widening of the diagonal tension crack. For this reason the value of the nominal bond stress at failure depends on the effectiveness of the shear reinforcement of the beam, and the use of a fixed per- missible bond stress is shown to result in a greatly varying factor of safety.
