The results of experimental tests of lintel hybrid beams made of air concrete and prestressed concrete were presented in paper. Blocks of air concrete was a protective element for the construction one. The length of hybrid beams was 3.0 m, while total height 27 cm. It was assumed that hybrid beams will work in the simply-supported scheme (with a 10 cm support) loaded uniformly over the entire length. The object of the tests were beams with the same geometry differing in the position of the prestressed wire. In the first considered case the wire was located at a distance of 6.5 cm from the bottom edge of the construction part (prestressed concrete) of beam, while in the second case: 13 cm from the bottom edge of the construction part of beam. The experimental tests under static monotonous load up to the failure were examined. The paper shortly described the designing stage of project. Hybrid beams were calculated with Limit State Method and Allowable Stress Method. Some assumptions for element calculations were also presented.
