This work presents the numerical results of the mechanical behavior of a new concrete-composite beam under bending loads. The proposed design consists to integrate a tubular polymer member in the flexural tensile zone, wrapped by a GFRP composite Jacket, which mobilizes a lateral confinement pressure. An analytical modeling based on classical beams theory is carried out in order to assess the strains field and the stresses propagation of the cross-section using the non linear laws behaviour of all constitutive materials. In order to allow for a better understanding of analytical observations, a finite element model was performed to determine the flexural capacity and the failure modes. The effectiveness of the new concrete-composite beam design is highlighted by the comparison of obtained results to conventional reinforced concrete ones, in terms of strength and ductility.
