The ACI and CSA design codes offer no unified method for evaluating the
deformability of fiber-reinforced polymer (FRP) reinforced-concrete (RC) structures, although
numerous experimental results for such elements are available. This study discusses the
methods for quantifying the deformability in FRP-RC structures. The methods were assessed
based on the experimental results of four full-scale RC shear walls: three reinforced with
FRP bars and one with steel bars
