This research is achieved in the general frame work of the study of the concrete behaviour. It has for objective the development of a numerical tool able to predict the behaviour of confined reinforced concrete columns with circular and square cross sections under increasing compressive load. The concrete behaviour is assumed as elastic - plastic model with associated flow rule in compression region and as elastic with tension stiffening behavior in the tension region. Two failure criterions have been taken into account according to the Drucker - Prager and Rankine criterion. An elastic strain hardening model has been used for the reinforcing steel. A finite element method using solid cube elements for concrete, and bar elements for the reinforcement has been adopted. Good agreement has been observed in comparing numerical results with those issued from the literature.
