This paper proposed hybrid (steel/glass fiber-reinforced polymer (GFRP) composites) bars as primary reinforcement for modern reinforced concrete (RC) columns. A detailed two-dimensional finite element model (2D FEM), that considers material and geometric nonlinearity and the bond behavior of steel and glass FRP (GFRP) reinforcement, was created, and validated against the available experimental results. The built model predicted the experimentally obtained results representing in failure mode and deformation response with good accuracy. Hybrid system that consists of steel/GFRP combination was then studied. The results patently showed that hybrid reinforced columns can undergo large displacement with minimal damage. This; however, can be guaranteed through carefully selection of reinforcement arrangement.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
