 This study aims to investigate a new shear reinforcement method using thin mild steel, TMS, plates instead of conventional shear links in deep beams. The results showed that the 2.0 mm thick TMS plate had the highest load carrying capacity among the 13 reinforced concrete deep beam specimens tested. Furthermore, the perforated plates with a three-column hole arrangement exhibited the best performance in terms of load carrying capacity, with a 2.9% increment compared to the control beam specimen. The specimens also demonstrated comparable elastic stiffness with the control beam, indicating that TMS plates can potentially replace conventional shear links in deep beams. Additionally, this proposed method changed the failure mode from conventional diagonal shear tension failure to a combination of flexural failure and shear deformation. Finally, a numerical model was developed and found to have a good correlation with the experimental results, suggesting potential for use in future parametric investigations on deep beams and cost reduction in future experimental work.
