Flexural Retrofitting of R.C Beam Using Hybrid Laminates

Mohamed Asick Umar.H, Manikandan.T

Abstract: Reinforced concrete (RC) structure using externally bonded fiber reinforced polymer (FRP) components has become a very worldwide practice, extensively accepted by recent design codes. In particular, the flexural strength of a reinforced concrete beam can be broadly increased by application of carbon, glass FRP sheets adhesively bonded to the tension face of the beam. In this experimental study, a total of nine beam specimens (1000 mm x 150 mm x 200 mm) of M 20 grade concrete are casted and preloaded with 75 % of ultimate load by two point load method, later retrofitted with hybrid laminates (GFRP+CFRP) of different thicknesses at U-wrap bonding technique used to examine the flexural behavior of RC beam.. A comparative study is to be made with the test results.
