Shape memory alloy (SMA) is known as an attractive metallic material that illustrates two unique properties. First, the shape memory effect (SME) refers to the capability of high recovery stress (pre-stress) in the martensitic phase by heating. Second, the superelasticity effect (SE) refers to the recovery of its original shape after stress removal in the austenite phase. There are three main categories of SMA consisting of Cu-based, Fe-based, and Ni-Ti. Recently, due to the economic concern, especially the Ni-Ti-based, the use of these materials is very limited in civil engineering applications. The objective of this paper is to examine the potential of SMAs in enhancing the performance of concrete columns, specifically in terms of strength, durability, and resistance to seismic activity. Through analysis of relevant studies, this review discusses the various techniques involving SMAs, evaluates their effectiveness, and addresses the associated challenges. The findings of this review provide valuable insights into the advantages and limitations of employing SMAs to improve the behavior of concrete columns, serving as a valuable resource for researchers and engineers engaged in the design and construction of resilient structures.
