Annotation: Concrete, smooth and fluted corrugated bar reinforcement, flat and fluted sheet steel, shaped roof deck are used, as a rule, for prefabricating reinforced concrete beam structures with external sheet (ribbon) reinforcing. However the scientists passed by the rather interesting type of sheet reinforcement called cut-stretching sheet. Due to its particular geometrical shape of lateral surface and strength features cut-stretching sheet can also be used as external reinforcement in reinforced concrete structures. Good adhesion between concrete and steel without using additional connecting items and strength of structure are provided by this type of reinforcement. It also decreases stress-strain behavior of concrete tension zone and solidity of reinforced concrete. The experimental results of researching of reinforced concrete beam specimen reinforced by cut-stretching sheet are provided in the article. The influence of available or unavailable covering concrete layer on crack resistance, stress-strain behavior and bearing capacity has been found out.

Keywords: steel concrete beam, crack resistance, crack opening displacement width, cut-stretching sheet.
