Reinforced concrete (RC) walls are mainly used in RC structures to resist gravity and lateral forces. These structural elements may need be upgraded withstand additional forces extend their life cycle. Therefore, it is crucial provide effective strengthening techniques using low-cost sustainable materials under optimal conditions rehabilitate walls. This study presents an experimental numerical investigation of reinforced normal (NC) strengthened with near-surface mounted (NSM) steel bars, confined or without externally bonded (EBR) galvanized sheets (GSSs). A total six were constructed, loaded, tested failure. The examined parameters included the type technique, used, position configuration strengthening. Both EBR NSM applied GSSs respectively. configurations introduced vertical horizontal positions forces, experiments revealed that these significantly influenced crack control, energy absorption, mode collapse, ultimate load capacity. Nonlinear three-dimensional finite element models developed verified against results, achieving a validation accuracy 95% on average. was followed by parametric investigating effect confinement reinforcements. results confirmed could increase capacity from 20% 38%.
