FRP Structural Strengthening

Fiber Reinforced Polymer (FRP) is used for Structural Strengthening of concrete and masonry structures.
FRP is a composite material that is made up of  fiber (carbon or glass) and an epoxy resin.
FRP composites are designed to meet critical industry/engineering requirements for strength and durability.

These FRP composite materials include:

  • Carbon Fiber Strips
  • Carbon Fiber Fabrics
  • Glass Fiber Fabrics
  • Carbon and Glass Fiber Rods

The reasons for strengthening of reinforced concrete structures are numerous:

  • Change of use of a building
  • Increased live and wheel loads
  • Installation of heavy machinery
  • Modifications to a building such as elimination of walls/columns or openings cut through slabs
  • Code changes
  • Structural damage
  • Corrosion of steel reinforcement
  • Errors in design or construction

FRP Composites are commonly used in the engineering/construction industry today because the offer a number of distinct advantages for structural strengthening:

  • Lightweight
  • Non-corrosive
  • Very high tensile strength
  • Easy to handle
  • Low in place installation costs
  • No or minimal structure downtime
  • Economical to use

FRP is used for a number of structural strengthening applications:

  • Columns & Tanks – confinement/flexure/shear strengthening
  • Beams – flexure/shear strengthening
  • Slabs – flexure/bending moment strengthening
  • Walls – in and out of plane strengthening
