Strength and Ductility Performance of GFRP Laminated RC Beams with Discrete Steel Fibres | Chapter 02 | Novel Perspectives of Engineering Research Vol. 5

 Many studies have found that reinforced concrete (RC) beams reinforced with externally bonded fibre reinforced polymer (FRP) laminates/sheets lose ductility as a result of increased stiffness, resulting in debonding type failure without any warning. The goal of this study is to investigate the strength and ductility of glass fibre reinforced polymer (GFRP) laminated RC beams with varying volume fractions of discontinuous steel fibres (Vf = 0.5, 1.0, and 1.5). Load and deflection at yield and ultimate stages, ductility, crack-width, and failure mechanism were among the metrics studied. According to experimental results, the addition of steel fibres improves the strength and ductility of FRP-strengthened beams at all volume fractions utilised in this study. To forecast the reaction of all beams, full-scale beam models based on finite element analysis were built using ANSYS software, and the load-deflection behaviour of the models matches well with the experimental data.
