Uniaxial cyclic and monotonic compression tests were carried out on partially and fully wrapped concretecylinders with Carbon Fibre Reinforced Polymer (CFRP) wet lay-up sheets. The influence of the concretecompressive strength, CFRP stiffness, geometric confinement arrangement and loading type on thecompressive behaviour of reinforced concrete column elements of circular cross section up to their failurewas assessed. A uniaxial stress-strain constitutive model is proposed, and the results obtained from theexperimental tests were used to calibrate some of the parameters of this model, and to appraise the modelperformance. This model allows the simulation of reinforced concrete members by using Timoshenkoone-dimensional elements, in the context of the finite element method (fibre model). Good agreement wasobtained between numerical simulations and experimental results for both monotonic and cyclic loadingtests.
