About Fiber reinforced polymers

The mechanical properties of FRP reinforcing bars differ from those of conventional steel rebar in a number of areas. As a result, several issues arise in the development of a design methodology for concrete structures reinforced with such bars. The general design recommendations for flexural concrete elements reinforced with FRP reinforcing bars are presented in ACI 440.1R-06 (2006), Guide for the Design and Construction of Structural Concrete Reinforced with FRP Bars, as reported by the American Concrete Institute (ACI) committee 440.

American Concrete Institute (ACI) suggests the following guidelines for the use o the FRP:
