The public education project ""Dream School"", implemented in support of the federal school overhaul program, attracts students of architectural and design schools in the regions, which will allow them to simultaneously acquire applied competencies in the learning process. During the development of the design project, the need for specialists to conduct a preliminary design analysis was revealed, since one of the five schools did not meet the standards in terms of their spatial planning parameters. It is proposed to carry out the reconstruction of this educational institution. The premises of the dining room and the assembly hall are transferred to the annex block.

The article presents a way to increase the load-bearing capacity of a reinforced concrete column due to metal clips from the corners with an increase in the load on it. To ensure the joint operation of the existing column and the metal cage, the corners are subjected to prestressing, which is achieved by compressing the corners with jacks.

The compositions of class B15-20 peplotuf concrete on tuff ash and crushed stone with the use of a plasticizer for use as a structural and thermal insulation layer in two-layer wall panels are proposed. The calculated heat transfer resistance of a two-layer structure is determined, and the dependence of the density and strength of the mixture on the cement consumption per 1m3 is established.

The article presents a new design of reinforced concrete I-beam coverage with prestressed reinforcement, in which the ribs are stretched zone side ledges. This solution allows you to pick off high-strength prestressed reinforcement along the length of the element, thus increasing the ratio of reinforcement used in comparison with a standard solution
Keywords: reinforced concrete beam is equal to the resistance of prestressed reinforcement, combined prestressing
