confined concrete

confined concrete

A concrete which has closely-spaced special transverse reinforcement which restrains the concrete in directions perpendicular to the applied stress.

Deniaud and Neale (2006) observed a good agreement between the elasto-plastic analysis of FRP-steel confined concrete columns with the D-P yield criterion and experimental data.
Assumption (5) is not exact but however a fairly reasonable assumption in the sense that: (i) at small concrete strains, the variation of confining pressure would not have significant effect on the confined concrete stress (Attard and Setunge 1996); (ii) when the extreme fibre of confined concrete reaches about 0.
the increase in ductility of confined concrete is related to the stiffness of the confining device.
