In civil and structural engineering, building structures with vigorous stability and strength utilizing economical materials is challenging. Stability of structures during their lifespan is a very demanding endeavor in civil engineering systems. Recent trends are highly focused on high strength materials, strong corrosion-resistance in structural elements, slender structure development, broad span provision, and load reduction. in order to achieve these conditions, composite materials have proved to be a successful aspirant. The fiber-reinforced polymer (FRP) possesses novel properties that encourage the researchers to strengthen or restore the structural degradation of the reinforced concrete (RC) columns via confinement. The present study highlighting the different aspects of (FRP) confined (RC) column having different aspect ratios, the axial load, and the high temperature under extensive literature review. The FRP confinement is much more effective in the case of circular columns than sharp-edged rectangular columns. The variation of the cross-sectional aspect ratio (section depth to width ratios) of RC columns plays a vital role in the evaluation of the efficiency of strengthening techniques. In spite of the clear and proven advantages of utilizing FRPs over conventional materials, awareness of the behavior of such composite materials after exposure to high temperature is noticeable and requires more research.
