Investigation of Bond Strength Between GFRP Wrapped Steel Reinforcement and Concrete with Pullout Test
The bond behavior of glass fiber reinforced plastic (GFRP) wrapped deformed steel reinforcements having corrosion resistant with concrete is one of the important factors affecting the flexural performance and ductility of structural member exposed to bending. However, the number of studies on the bo...

| description | The bond behavior of glass fiber reinforced plastic (GFRP) wrapped deformed steel reinforcements having corrosion resistant with concrete is one of the important factors affecting the flexural performance and ductility of structural member exposed to bending. However, the number of studies on the bond of these reinforcements with concrete is insufficient due to not existing so much investigation on this issue. In this study, resin-impregnated glass fibers were wrapped on deformed steel reinforcements and new composite reinforcements of three diameters were produced, and these composite reinforcements bond with concrete were examined by pullout test. In addition, the bond of these composite reinforcements was compared with the bond of unwrapped deformed steel reinforcement. In this context, a total of 18 pullout tests were conducted in the study. As a result of the study, it is observed that maximum bond strength of FRP wrapped deformed steel reinforcements being not applicated surface deformation (ribs, wound, sand coated etc.) ranged from 0.41 times to 0.64 times according to unwrapped steel reinforcements. In addition, it has been observed that the GFRP wrapped steel reinforcements maintain their bond strength up to high slipping values after reached the maximum bond strength values, compared to unwrapped deformed steel reinforcements. |
