Shear Strengthening of T-beam with FRP

The rehabilitation of existing reinforced concrete (RC) bridges and building becomes necessary due to ageing,
corrosion of steel reinforcement, defects in construction/design, demand in the increased service loads, and damage
in case of seismic events and improvement in the design guidelines Fiber-reinforced polymers (FRP) have emerged as
promising material for rehabilitation of existing reinforced concrete structures. The rehabilitation of structures can be
in the form of strengthening, repairing or retrofitting for seismic deficiencies. RC T-section is the most common shape
of beams and girders in buildings and bridges. Shear failure of RC T-beams is identihed as the most disastrous failure
mode as it does not give any advance warning before failure. The shear strengthening of RC T-beams using externally
bonded (EB) FRP composites has become a popular structural strengthening technique, due to the well-known
advantages of FRP composites such as their high strength-to-weight ratio and excellent corrosion resistance.
