The paper deals with the work of statically indeterminate two-span beam with a combined reinforced by the action of concentrated forces. The nature of the stress-strain state of beams with combined reinforcement based on a three-dimensional model is investigated by the computer modeling. Three series of samples were investigated totally. The study obtained numerical results of continuous beams reinforced with metallic and composite reinforcement. The dependence of the stress – strain state of increasing the percentage of the top reinforcement (composite) fittings. Obtained depending on the changes experienced beam deflection on the applied load on the stage loading. Shown in the lower voltage (decking) section stretched and compressed steel reinforcement and tension in the upper (reference) section stretched and compressed composite reinforcement stresses in the concrete surface with structural failure.
