There is an urgent need for models that can accurately predict performance
of В®ber-wrapped concrete columns. Axial compression tests on a total
of 45 carbon-wrapped concrete stubs of two batches of normal and
high-strength concrete and В®ve different number of wraps were used
to verify a conВ®nement model, which was originally developed for
concrete-В®lled glass FRP tubes. Also, a nonlinear В®nite element
model with a non-associative DruckerВ±Prager plasticity was developed.
Both models compared favorably with test results. It was concluded
that the adhesive bond between concrete and the wrap would not signiВ®cantly
affect the conВ®nement behavior. Moreover, the same conВ®nement model
can be applied to carbon and glass В®bers, as long as the model has
incorporated the dilation tendency of concrete as a function of the
stiffness of the jacket. However, it is of utmost importance to establish
the effective hoop rupture strain of the wrap through a reliability
analysis by setting proper conВ®dence level for design purposes.
