This paper presents the findings of an experimental data on the effects of inclined shear
reinforcement in reinforced concrete (RC) beam. Two types of shear reinforcement of RC beam
were investigated, conventional stirrups (vertical links) and inclined shear reinforcement (45
degrees of inclined shear reinforcement). The RC beam with conventional stirrups was
designated as a control specimen. The RC beams with different types of shear reinforcement
were tested for shear under four-point loading system. Comparisons were made between both
types of RC beam on load-deflection, load-steel strain, load-concrete strain behaviour and mode
of failure. The theoretical and experimental were calculated by using conventional formulation in
accordance to EC 2 in order to verify the experimental results. From the results, it was observed
that the RC beam with 45 degree inclined shear reinforcement improved structural performance
in shear by approximately 20% and thus prolong the shear failure behaviour as compared to the
RC beam with vertical links.
