Meanwhile, its contribution to the overall strength is, so far, not accounted in design provisions. Yet, comprehensive experimental and numerical studies are required to find out how important this contribution is. In this research, the relevant experimental studies available in literature is extended numerically to involve more parameters that affect the strength of RC-beam. The present parametric study involves, the amount and arrangement of SFR, the amount of main reinforcement, the amount of transverse shear reinforcement, the shear span-to-depth ratio, and the beam depth and width. Results of the study demonstrate that the contribution of SFR to the beam response is not only affected by SFR amount and arrangement, but also by the other parameters involved in the study. However, this contribution is generally significant; ignoring this contribution by design provisions results in conservative design. Hence, SFR contribution to strength of RC-beams is recommended to be taken into account in design provisions codes.
