| Abstract In the present work a formulation of the reinforced bars and prestressed tendons embedded in the brick element is developed and used for the nonlinear analysis of reinforced-prestressed concrete beams. The reinforcement and prestressing bars are represented by an axial 3 nodded bar elements embedded into the 20 nodded isoparametric brick concrete element. Perfect bond is assumed between concrete and prestressing steel bars (or tendons) such that displacements and strains of the bars are assumed to be compatible with those of the concrete element. To verify the applicability of the model two prestressed beams are analyzed and the numerical results show a good agreement with the experimental one.
