Figure Description:
This figure illustrates a Shallow-End Anchored EBFRP System applied to a hollow-core slab, designed for structural strengthening without deep drilling or invasive anchoring. Key elements include:
- Externally Bonded FRP Strips laid across the hollow-core slab surface, aligned to the stress flow paths to enhance flexural performance.
- Shallow Anchors at One End—visible at slab edges—where anchorage depth is limited due to the voids within hollow-core units. These anchors improve local stress distribution and resist peeling forces.
- Void-Aware Placement ensures anchorage does not compromise the structural integrity of the prestressed slab’s internal hollow cores.
- Minimal Invasion Configuration makes this system ideal for retrofitting precast floors or bridge decks where internal drilling depth is restricted.
This system is commonly evaluated for use in prefabricated/prestressed elements where traditional anchoring methods are not feasible.
