Numerical Study of Compressive Members of FRP Hybrid Reinforced Concrete and its Modeling Under Concentric Loading

One of the challenges of using reinforced concrete structures is the corrosion of reinforcements in aggressive and corrosive environments such as offshore structures, stairs, etc., which will eventually lead to the destruction of concrete structures. To solve the corrosion problem in this category of structures, experts turned to the use of rebars with epoxy coating as a suitable alternative to conventional rebars. Most FRP rebars on the market today are made of high-performance continuous fibers such as glass, carbon and aramid, which are embedded in a polymer substrate by various composite production methods. FRP amplifiers are commonly used in various forms in the form of networks, rebars, textiles or cables. In this research, the numerical behavior of FRP hybrid reinforced concrete compression members and its modeling under concentric loading is investigated. All modeling is performed in ABAQUS finite element software and is evaluated using nonlinear analysis.
