Aspects of Deformability of Concrete Shear Walls Reinforced with Glass Fiber–Reinforced Bars
Publication: Journal of Composites for Construction
Volume 19, Issue 5
Abstract
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. The objective was to contribute to the development of a method for verifying the deformability of FRP-RC structures. The curvature ductility index () and deformability index () were found to be the most appropriate methods when calculated at a concrete strain equal to 0.0035.
