Composite columns are columns consisting of a base section and one or more reinforcing sections (filler or filler). The components of a composite do not combine chemically so that the components fully retain their chemical and natural nature, and there is a certain common surface between the components. In terms of the reinforcing section, composites are divided into fiber-reinforced composites (FRC) and particle-reinforced composites (PRC). FRP composite profiles are composite materials that are obtained from carbon, glass, or aramid fibers embedded in a polymer resin (epoxy resin or polyester resin) and as a suitable alternative for areas where the use of steel profiles due to severe corrosion and Or the existence of strong magnetic fields is impossible. Common composite columns are a combination of concrete and composite steels, including FRP rebars and other types of composite rebars. In this research, the study of structural columns made of fiber reinforced concrete (FRP) surrounded by fiber-reinforced polymers (FRC) is presented. Modeling will be performed using Abaqus finite element software. After performing numerical analysis, it was found that fiber concrete has a better and better functional behavior than the column with ordinary concrete, and also, the effect of reinforced fibers increases the compressive strength of the column.
