“…23,24 Increasing the strain capacity by an order of magnitude is certainly feasible. Concrete-filled steel tubes were used in the 1960s, 25 but suffer from Poisson's ratio effects which reduce the effectiveness of the confinement. The use of glass fibrereinforced plastic (GFRP) tubes, formed by filament winding with a low helix angle, overcomes these problems, and allows very high strain capacity.…”

Knowledge of the properties of advanced composites leads to conclusions about the most logical ways in which they can be used. The paper considers the elastic properties, the bond properties and the lack of ductility, and concludes that structures should be designed as over-reinforced, with partially bonded internal tendons, and resin-free external tendons. It concludes that enhancement of the compression zone is possible by fibre-reinforcing or confining the concrete, and that requirements for shear need to be totally reworked in the absence of plasticity. It considers the economic justification of advanced composites in concrete, and concludes that innovation is still required, but now on a commercial scale.
