These columns are usually subjected to axial force and bending moment due to the self weight of the tower and the wind load on the steel structure and the antennas or electric accessoriesThe behavior of FRP bars in compression plays an important role in assessing the column capacityMany investigations have been carried out on the flexural behavior of concrete members reinforced with FRP barsComparatively little attention has been directed toward the use of these bars in axial or eccentric loadingReinforced concrete columns subjected to eccentric loads are often used to support electrical and telecommunication steel towersDeteriorated columns due to corrosion of steel are very common in this type of constructionThe use of FRP bars as a main reinforcement in these columns can be a cost - effective alternative to overcome the corrosion problemHowever , the low modules of elasticity of the FRP bars , the reduced compressive strength compared to their tensile strength , and their non - yielding characteristics are main issues that may affect the behavior of these columns
