This paper discusses an experimental study examining size effect in GFRP RC beams with overall height varying from 260 mm to 460 mm, but otherwise similar in geometry and material properties. All beams were unreinforced in shear and designed to ensure shear failure. 3D DIC was employed alongside strain and displacement transducers to gain additional insight into the development and degradation of shear resisting mechanisms. The experimental measurements will be used to calibrate a numerical model and validate its reliability and performance. The results of this study can assist in improving existing shear design recommendations for FRP RC beams.

Abstract
This paper discusses an experimental study examining size effect in GFRP RC beams with overall height varying from 260 mm to 460 mm, but otherwise similar in geometry and material properties. All beams were unreinforced in shear and designed to ensure shear failure. 3D DIC was employed alongside strain and displacement transducers to gain additional insight into the development and degradation of shear resisting mechanisms. The experimental measurements will be used to calibrate a numerical model and validate its reliability and performance. The results of this study can assist in improving existing shear design recommendations for FRP RC beams.| File | Dimensione | Formato | |
