ABSTRACT
A number of committee activities from professional organizations around the world address the use of FRP materials in civil structures. These activities have resulted in publishing several codes and standards relevant to FRP as primary reinforcement for structural concrete. FRP codes and standards have been in development since the 1980s. Due to the different properties of FRP materials in comparison to conventional steel bars, FRP warrants separate treatment in these specifications. FRP materials have relatively low modulus of elasticity and are characterized by high tensile strength only in the direction of the reinforcing fibers. Furthermore, FRP materials do not yield; rather, they are elastic until failure without showing any ductile performance.
