A computational model of deformation of a flat-stressed reinforced-concrete composite element in the contact zone is proposed. Deformation equations takes the form of the relationships between the final increments of stresses and deformations for a corrosion-damaged reinforced concrete element with intersecting cracks. Coefficients of flexibility matrix of the element are obtained. These coefficients take into account the long-term deformation, corrosion damages and concentrated shear, when intersecting cracks appear in the contact zone of the composite element. The solution to reinforced-concrete beam of composite section is given. The computational results are compared with the experimental data for such structures.
