Modeling Of Shear Strengthening Of Reinforced Concrete Beams Retrofitted With Externally Bonded Fiber Reinforced Polymers, Srinivasa Anusha Bellamkonda

LSU Master's Theses

This thesis presents a study on the shear retrofit of reinforced concrete (RC) beams with externally bonded fiber reinforced polymers (FRP), since it is very important for RC beam to have a shear strength that is higher than the flexural strength in order to ensure ductile flexural failure mode. The study proposes a new model to predict the FRP shear strength contribution for different modes of failure, i.e., bending, shear with FRP rupture, shear with FRP debonding, and mixed shear-flexure and various retrofit techniques, i.e., side-bonding, U-jacketing, and full wrapping. The proposed model is compared to other existing models for …
