Wood is one of the most popular renewable natural materials. Nowadays, raw wood is hardly ever used in the construction industry. It has been substituted by glued laminated wood that is processed with the use of high-tech methods, thus eliminating the principal flaws and defects of the natural material. The deformability of glued laminated beams with combined reinforcement has been studied, under which the steel reinforcement of the periodic profile was placed in the dappings of the upper compressed zone, while ribbon-reinforced composite was glued to the bottom of the stretched zone. The graphical charts for the layer change of the deformations of wood, steel, and composite reinforcement from the beginning of the loading application to the moment of destruction are presented.

One of the ways to eliminate the negative shortcomings of wood (dependence of its properties on the structure, defects, the need for use and significant consumption of quality lumber, excessive mass of sections, creep under prolonged load, etc.) and increase technical and economic efficiency is reinforcement of solid and glued trees, steel or composite plastic fittings. This allows you to significantly reduce wood costs, reduce installation weight, improve the quality and reliability of wooden structures that work mainly on the bend. The expediency of reinforcing elements of solid or glued wood with steel and composite polymer reinforcement is substantiated. The rather high compatibility of wood work in the compressed and stretched zones of the bending element of steel reinforcing steel of classes A400C, A500C and composite fiberglass reinforcement, composite basalt reinforcement and composite carbon tape is shown. Reinforcement of solid and glued cross-sectional elements of wooden structures with steel or composite plastic reinforcement or tape can significantly reduce wood costs, reduce height and installation weight, improve quality and reliability. Analysis of the current state of research of reinforced wooden structures indicates the need for a thorough study of the bending of wooden beam elements with combined reinforcement of steel and composite reinforcement and with combined pre-stressed reinforcement. To date, the issue of studying the stress-strain state of reinforced wood in the "calculated cross section" of both the structure and the work of the material in its composition is insufficiently covered. The use of reinforced wood in structures is not regulated by most countries, so there is no general theory of calculation of reinforced wood structures, which would be based on sound clear hypotheses and assumptions and would be based on the basic principles of solid mechanics.

A detailed analysis of literary sources on the study of strengthening of wooden elements by various methods was carried out. The calculation sequence of wooden elements reinforced with glued metal elements is proposed. An algorithm for determining the "moment-curvature" graph using optimized wood deformation diagrams is proposed. Calculations were carried out for various forms of beam cross-sections. Calculations of the cross-section were carried out and "moment-curvature" graphs were determined for different options for the reinforcement of the wooden element (with the reinforcement of the compressed zone, the stretched zone, as well as with the reinforcement of both zones). Schedules were determined with different percentages and methods of reinforcing elements. It was established that the best result of reinforcement occurs when reinforcing compressed and stretched zones, less effective when reinforcing a beam in a compressed zone, the smallest effect of reinforcing a stretched zone. To simulate the work of reinforced wood, the mechanical characteristics of "pine" wood with a moisture content of 12% and metal, namely the characteristics of A400S reinforcement, were used. Moment-curvature plots are given for cross-sections with different percentages of reinforcement and reinforcement in compression and tension zones. An increase in the load-bearing capacity of a bending wooden element due to various options and percentages of reinforcement reinforcement is presented. It is necessary to note the change in the shape of the "moment-curvature" graph with symmetrical reinforcement, namely, with an increase in the percentage of reinforcement, its shape approaches a straight line. Based on the analysis, conclusions were drawn. The volume of further experimental and theoretical research on this issue is given.
