Enhancing the EB-FRP strengthening effectiveness by incorporating a cracking-control layer of ECC with different thicknesses

Construction and Building Materials, 2021
The multiple and tight cracking nature of engineered cementitious composite (ECC) under tension can significantly mitigate or eliminate the premature debonding of externally bonded (EB) fiber-reinforced polymer (FRP).

Behavior of FRP-engineered cementitious composite layer and concrete interface with FRP anchors

Engineering Structures
The problem of low material utilization caused by premature interface debonding is prevalent in carbon fiber-reinforced polymer (CFRP)-reinforced concrete structures. In this study, the influence of anchors on the bonding and behavior of the FRP-engineered cementitious composite (ECC) layer and concrete interface was analyzed.

Delamination buckling of FRP layer in laminated wood beams

Composite Structures, 1997
An analytical solution for predicting delamination buckling and growth of a thin fiber reinforced-plastic (FRP) layer in laminated wood beams under bending is presented. Based on a strength-of-materials approach, displacement functions for a delaminated beam under four-point bending are derived. Using force and displacement compatibility conditions, an

Debonding of FRP plated concrete: A tri-layer fracture treatment

Engineering Fracture Mechanics, 2006
A tri-layer interface fracture energy model is developed to facilitate the quantification of various debonding scenarios in fiber reinforced polymer (FRP)/epoxy/concrete plated systems. The work is motivated by the relatively thick adhesive bond line generally encountered in such retrofitted systems.

Effect of steel–FRP ratio and FRP wrapping layers on tensile properties of glass FRP-wrapped ribbed steel reinforcing bars

Materials and Structures, 2021
One of the many alternative methods developed to address the corrosion problem of steel reinforcements is the use of hybrid reinforcement composed of a fiber-reinforced polymer (FRP)-wrapped ribbed steel reinforcing bars. However, the number of layers and thickness of the FRP wraps on the ribbed steel core affect the mechanical properties of the glass ...

A CNN-integrated percussion method for detection of FRP–concrete interfacial damage with FEM reconstruction

Structural Health Monitoring, 2022
Reinforced concrete (RC) structures are commonly strengthened using externally bonded fiber-reinforced polymer (FRP) sheets. The bond between the FRP and concrete is a crucial factor affecting the strengthening effect, and debonding along the FRP ...
