Effect of GFRP Stirrup Confinement on the Bond Strength of GFRP-RC Beams [PDF]
International Journal of Concrete Structures and MaterialsThe current provisions for development length in the ACI 440.11 code disregard the confinement effect provided by stirrups on the bond strength of longitudinal bars and require splice lengths that pose implementation challenges.

Development Length of GFRP Bars [PDF]
Journal of the Korea Concrete Institute, 2010 The objective of this study was to propose a development length equation for GFRP bars. A total of 104 modified pullout tests were completed while the test variables were embedment length (15, 30, ), net cover thickness (), top-cast bar effect, different GFRP bar types (K2KR, K3KR and AsUS), and bar diameters (10, 13, 16 mm). Average bond stresses were

Pultruded GFRP Reinforcing Bars Using Nanomodified Vinyl Ester [PDF]
Materials, 2020 Glass fiber-reinforced polymer (GFRP) reinforcing bars have relatively low shear strength, which limits their possible use in civil infrastructure applications with high shear demand, such as concrete reinforcing dowels. We suggest that the horizontal shear strength of GFRP bars can be significantly improved by nanomodification of the vinyl ester resin

GFRP Bars Anchorage Resistance in a GFRP-Reinforced Concrete Bridge Barrier [PDF]
Materials, 2019 In the present paper, experimental and numerical investigations were conducted on concrete bridge barriers utilizing glass fiber reinforced polymer (GFRP) bars with a hook at their ends. Implementation of these hooked bars instead of the bent bars or headed-end bars in the bridge barriers presented in the Canadian Highway Bridge Design Code (CHBDC) was
