GFRP Rebar Design Codes

Why design with Glass Fiber Reinforced Polymer (GFRP) Rebar?

The expensive cycle of maintaining, repairing and rebuilding infrastructure has led owners to seek more efficient and affordable solutions in the use of fibre-reinforced polymers (FRPs). These lightweight, high-strength composite materials are resistant to corrosion, durable and easy to install.

FRPs are already increasing infrastructure service life and reducing maintenance costs.

Infrastructure owners can no longer afford to upgrade and replace existing infrastructure using 20th-century materials and methodologies. They are looking for emerging new technologies such as FRPs that will increase the service life of infrastructure and reduce maintenance costs.

They [GFRP rebars] are rapidly becoming the materials of choice over steel for reinforced concrete structures. Despite their relatively recent entry into civil engineering construction, FRP-reinforced concrete structures are gaining wide acceptance as effective and economical infrastructure technologies.

Indeed, the most remarkable development over the past few years in the field of FRPs has been the rapidly growing acceptance worldwide of these new technologies for an enormous range of practical applications. 

The goal is to optimize the use of FRP materials so that stronger, longer-lasting structures can be realized for minimum cost.
