Figure Description:
This figure depicts a Single-End Anchored Externally Bonded Fiber Reinforced Polymer (EBFRP) System, used for structural strengthening tests at slab-wall interfaces. The system includes:
- Externally Bonded FRP Laminates arranged across the slab surface and extended toward the wall, designed to enhance flexural capacity and surface confinement.
- Anchorage Applied Only at One End of each FRP strip (visible as fan-like anchor zones at the wall face), allowing for evaluation of bond performance and stress transfer with minimal anchorage intervention.
- Unanchored Free Ends simulate real-world conditions where full anchorage is not feasible or intentionally omitted for research purposes.
- Reinforced Boundaries with vertical and horizontal reinforcement cages (in red) and a rebar mesh system to replicate realistic structural detailing in test specimens.
This configuration is commonly used in bond behavior studies and pull-off or shear transfer tests to assess the effectiveness of single-side anchoring in preventing premature debonding and enhancing durability in FRP-retrofitted concrete elements.
