Reinforced concrete is the most widely used construction material for building structures. However, the durability of this material is reduced due to various factors such as the cracking of concrete and corrosion of steel reinforcement. Fiber Reinforced Polymer (FRP) material, which is highly evaluated for its applicability as a concrete reinforcement, is known to be effective in enhancing the durability of structures. In this study, previous research on concrete column reinforced with carbon fiber reinforced polymer (CFRP) grid was reviewed. By analyzing these studies on replacing steel hoop, a concrete column reinforcement, with CFRP grid, it could provide reference data for future research on CFRP grid reinforced concrete columns and basic data necessary for designing CFRP grid reinforced concrete columns. The concrete column that replaced the steel hoop with the CFRP grid was divided into three categories: the column under concentric loading, the column subjected to bending and axial force, and the lateral confinement effect of the column. As a result, regarding behavior characteristics, there was no difference between ordinary steel hoop and CFRP grid; therefore, the possibility of substituting CFRP grid for ordinary steel reinforcement was confirmed. However, brittle fracture of the CFRP grid was observed during this experiment; further research on the improvement of joint strength of the CFRP grid edge joint is needed. Upon analyzing the proposed equation for the lateral confinement effect, it was found that the equations for estimating the ultimate strength of confinement concrete suggested by previous researchers could even be applied for the CFRP grid reinforced concrete column.
