This research studies the structural behavior of self-compacted reinforced concrete deep beams by using steel plates as an alternative to traditional shear reinforcement. Seven specimens were fabricated and tested to evaluate the effectiveness of steel plate substitution based on force equivalency principles. The experimental program includes one specimen with traditional stirrup reinforcement as a control specimen and six specimens divided into two groups. The first group included three beams with web reinforcement substituted with 2 mm, 3 mm, and 4 mm steel plates. The second group included three beams with skin reinforcement replaced by steel plates of the same varying thicknesses. Experimental results showed that using 4 mm-thick web steel plates enhances the load-carrying capacity by 11% compared to the control specimen. Other specimens, especially those with skin reinforcement steel plates, showed comparable performance to the control beam, suggesting that steel plate substitution maintains structural integrity without significant strength degradation. Finite element analysis was carried out using ABAQUS software to validate the experimental results. The numerical outcomes showed good agreement with those from the experimental program in terms of ultimate load capacity. The study concludes that steel plates can serve as a viable alternative to traditional shear reinforcement in self-compacting concrete deep beams, with optimal performance achieved using 4 mm-thick web steel plates.
