Abstract
Strengthening of reinforced concrete (RC) columns may be required to facilitate additional load-carrying capacity or for retrofitting purposes. However, traditional strengthening techniques, such as FRP confinement is prone to brittle failure and exhibits durability issues whereas steel/concrete jacketing increases column cross-section and weight. This study explores an innovative strengthening method for RC columns using near-surface-mounted (NSM) high-strength steel wires to enhance confinement. Experimental tests were conducted on eight RC columns under axial compression, evaluating various reinforcement configurations, namely horizontal wires, combined horizontal-diagonal wires, and embedded-end anchorage. The results showed the load capacity of the columns increased by 38–65 %, and energy absorption by 175–404 %. Columns strengthened with combined horizontal and diagonal reinforcement showed better structural performance than other configurations. Numerical simulations are also carried out using Abaqus and validated against the experimental findings.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
