I am looking for the steps to analyze and design retrofitted reinforced concrete T-beams using FRP techniques w/ or w/o carbon fibers. Your answers will be appreciated!
The portion of the slab which acts integrally with the beam to resist loads is called the Flange of the T-beam or L-beam. The portion of the beam below the flange is called as Web or Rib of the beam. The intermediate beams supporting the slab are called T-beams and the end beams are called L-beams.
Retrofitting Methods for RCC Structural Members
Fiber Reinforced Polymer(FRP) composites.
External plate bonding.
Near Surface Mounted FRP bars or Strips.
Section enlargement.
External post-tensioning.
Grouting.
Epoxy Injection.
Dear Ali Reza Daneshkhah kindly look at these papers, it will be useful:

I have attached a recent research article, where all the information which you are looking for has been nicely presented. This article not only covers the experimental investigation of strengthened T beams, but also presents the finite element modelling. Therefore, I hope, it will definitely help you a lot.
