Abstract:

In the design of highway bridges in Florida, glass fiber reinforced polymer (GFRP) materials are starting to replace mild carbon steel as the basis for reinforcing structural concrete components. Whereas traditional steel rebar is susceptible to corrosion, GFRP rebar is not, and therefore the use of GFRP has the potential to reduce maintenance costs and mitigate the need for corrosion-related structural rehabilitation. Moreover, GFRP rebar is lightweight in comparison to steel rebar, and consequently its use can simplify construction processes and reduce construction costs. However, GFRP does not possess the ductility that is associated with yielding of mild steel rebar. Instead GFRP is linearly elastic until failure. Additionally, the elastic modulus of GFRP is approximately one-quarter that of steel, resulting in reduced system stiffness. Designing GFRP reinforced concrete elements must therefore include consideration of how these material differences may alter structural performance and failure modes.
