“…Moreover, it was observed that GFRP wire winding prevents buckling of the longitudinal reinforcement, vertical splitting of the lap splices and concrete spalling. Seo et al [90] also proposed another quick and easy-to-install method comprising a GFRP strip device which is composed of a strip of GFRP composite with a aluminium clip connector and proposed to attach it in the plastic hinge region of the column. The experimental results showed a significant improvement in the seismic performance of the strengthened columns in terms of strength, displacement ductility and energy dissipation capacity.…”

Sustainability necessitates the protection of infrastructure from any kind of deterioration over the life cycle of the asset. Deterioration in the capacity of reinforced concrete (RC) infrastructure (e.g., bridges, buildings, etc.) may result from localised damage sustained during extreme loading scenarios, such as earthquakes, hurricanes or tsunamis. In addition, factors such as the corrosion of rebars or ageing may also deteriorate or degrade the capacity of an RC column, thereby necessitating immediate strengthening to either extend or ensure its design life is not limited. The aim of this paper is to provide a state-of-the-art review of various strengthening and repair methods for RC columns proposed by different researchers in the last two decades. The scope of this review paper is limited to jacketing techniques for strengthening and/or repairing both normal- and high-strength RC columns. The paper also identifies potential research gaps and outlines the future direction of research into the strengthening and repair of RC columns.
