Bond between Cfrp Sheets and Concrete
This paper presents the findings of an experimental program aimed at investigating the strain distribution between Carbon Fiber Reinforced Polymer (CFRP) sheets and concrete. CFRP is used as externally bonded reinforcement for concrete structures to improve flexure and shear strength and confinement of concrete. The effects of bonded length, concrete strength, and number of plies (or stiffness)...
متن کاملDe Lorenzis, and A. Nanni, “Bond Between Near Surface Mounted FRP Rods and Concrete in Structural Strengthening,” ACI Structures
The use of Near Surface Mounted (NSM) Fiber Reinforced Polymer (FRP) rods is a promising technology for increasing flexural and shear strength of deficient reinforced concrete (RC) members. As this technology emerges, the structural behavior of RC elements strengthened with NSM FRP rods needs to be fully characterized, and bond is the first issue to be addressed. Bond is of primary importance s...
متن کاملSteel–CFRP Composite (CFRP Laminate Sandwiched between Mild Steel Strips) and It-s Behavior as Stirrup in Beams
In this present study, experimental work was conducted to study the effectiveness of newly innovated steel-CFRP composite (CFRP laminates sandwiched between two steel strips) as stirrups. A total numbers of eight concrete beams were tested under four point loads. Each beam measured 1600 mm long, 160mm width and 240 mm depth. The beams were reinforced with different shear reinforcements; one wit...
متن کاملPre-Cracked Concrete Shear Strengthened with External CFRP Strips
In reinforced concrete design, there are situations where transfer of shear across a specific plane needs to be considered. Examples of such situation include corbels, bearing shoes, ledger beam bearing, and a host of connection between precast concrete elements. In this study, the shear transfer behavior of reinforced concrete is investigated experimentally by conducting test on 6 precracked p...
متن کاملEffect of Impact Load on the Bond between Steel and CFRP Laminate
Carbon fiber reinforced polymers strengthen steel structural elements. These structural elements are normally subjected to static, dynamic and fatigue loadings during their life-time. CFRP laminate is commonly used structures under the subjected loads. A number of focused on the characteristics of CFRP sheets members under static, dynamic and fatigue loadings. is a gap in understanding the bond...
