Abstracts: GFRP reinforcing bars present many unique advantages such as high strength-to-weight ratio, electromagnetic neutrality, and ease of handling. Most beneficial is that, they are not affected by the electro-chemical corrosion. They can offer a great potential for use in reinforced concrete under conditions where conventional steel reinforced concrete has resulted in unacceptable serviceability problems. Unfortunately, the surface deformation and mechanical properties of GFRP reinforcing bars are dissimilar to those of steel reinforcing bars. Therefore, the design guideline for steel reinforcing bars may not fully manifest the case for GFRP reinforcing bars.
