Abstract
AbstractThe use of FRP bar reinforcement as a rust-resistant material is one solution to increase the resilience of reinforced concrete structures in the marine environment. Innovations in the use of FRP reinforcement need to be developed to improve quality and reduce construction costs by eliminating concrete cover and shear reinforcement. Removing the concrete cover and shear reinforcement in the beam can minimize the cross-sectional height without reducing the effective height of the beam and simplify the placing of concrete. To replace the shear reinforcement, GFRP sheets are installed in the shear span. To validate the flexural behavior of reinforced concrete beams using FRP rods without concrete cover with GFRP sheet shear reinforcement in the experimental study, a numerical analysis was carried out using the finite element method using abaqus cae software. Modeling and treatment of test objects in numerical analysis is based on modeling and experimental treatment studies including material data used are the same as those in experimental research. The results obtained are that the flexural load capacity of the BFTS analyzed numerically is 12.45% greater than the experimental study. BFTS crack pattern in numerical analysis is wider than experimental study because the load resisted is numerically larger but basically the crack pattern experienced in the mid-span zone is similar.KeywordsNumerical analysisExperimental studyGFRP sheet and GFRP bar
