Figure Description:
This figure illustrates a Multi-Anchored Externally Bonded Fiber Reinforced Polymer (EBFRP) System for structural retrofitting and reinforcement. The design integrates multiple anchorage mechanisms to enhance load transfer and mitigate common failure modes such as premature debonding. Key features include:
- Externally Bonded FRP Laminates arranged in orthogonal and diagonal configurations, ensuring multi-directional reinforcement of the concrete element.
- Fan-Type and Linear Anchors that provide mechanical interlocking and stress redistribution to improve the system’s anchorage efficiency.
- Embedded FRP Ropes and Anchors within drilled holes and around the concrete column and beam junctions, enhancing anchorage depth and confinement.
- Surface Preparation Mesh (orange grid) representing rebar positioning or textured preparation to improve bonding between concrete and the EBFRP materials.
- Cross-sectional Detailing emphasizes the comprehensive engagement of all bonded surfaces and anchors with the host concrete member, particularly around joints and load-critical zones.
This configuration is suitable for strengthening beam-column joints, slab systems, and foundation interfaces in both new and existing concrete structures under seismic and heavy load conditions.
