One of the priority areas of research is the creation of lightweight composite bendable structures based on wood. Composite multi-span wood-glued beams with the proposed reinforcement scheme are an experimental design and to date their operation is poorly studied. The essence of the proposed design is to form a glued beam in which fiberglass is placed in the adhesive seam between the boards. To perform the calculations, we set the model of a beam with three spans. The load is assumed to be evenly distributed over the entire length of the beam. A comparison of the structure to assess its rationality was carried out with an unreinforced glued beam with the same design scheme. In the course of the study, it was found that, in contrast to glued beams, the strength of composite beams with layer-by-layer modification increases by 14–17%, and the deformability decreases by 4–7%. The destruction of the beams occurs along normal sections, which eliminates the possibility of chipping and splitting in the supporting sections, i.e. ensures the reliability of the structures for the action of shear forces in the supporting sections, thereby increasing the reliability of the structure against collapse.
