Abstract EN
The shear behaviour of deep beams considers as the main parameter of their load capacities.
therefore, the understanding of shear behaviour improvement by using inclined stirrups is essential to optimum design of web stirrups for deep beams.
in this study, a numerical investigation is presented to describe the effect of inclined stirrups on the shear behaviour for reinforced concrete deep beams.
this study was preceded by two steps as a part of verification and parametric study.
in the first step, three beams were analysed with different arrangements of their stirrups.
two beams are reinforced with either vertical or inclined stirrups when there are no stirrups in the third beam.
the numerically load-deflection curves, cracking patterns, and load-maximum crack opening curves were presented for all analysed beams.
these numerical results were verified by the experimental study showing an excellent agreement between them.
in second step, another 16 beams within 4 groups were analysed to show the parametric influence of using inclined stirrups.
this parametric study presented the effect of main reinforcement ratio, shear span-to-depth ratio, space between stirrups, and bar cross-sectional area of stirrups on the deep beams reinforced with either vertical or inclined stirrups.
the deep beam reinforced with inclined stirrups leads to a significant increase in the shear strength due to the contribution of these stirrups to restrict the opening of diagonal shear crack.
