Abstract
This project has made progress towards the development
of a novel alternative reinforcement technique for concrete
structures with complex geometries, which are difficult to
reinforce with conventional steel. Fibre-reinforced polymers
(FRP) are woven into geometrically appropriate reinforcement
cages to provide the required strength exactly
where it is needed. Automated fabrication of the reinforcement
utilises a modification of the filament winding technique.
Being extremely lightweight, the resulting wound-
FRP (W-FRP) cages are well suited to automation of the
construction process, as they can be delivered ready for
casting in optimized concrete elements. This is a key advance
in research progress towards achieving minimum
embodied energy, optimised, concrete structures. Experimental
tests conducted on full-size W-FRP reinforced concrete
beams demonstrate the reliability of the solution proposed,
showing a new frontier for sustainable and durable
reinforced concrete structures.
