The main trends of modern construction is the production and use of light construction structures, which can significantly accelerate the construction of building objects. At the same time, the use of structural and finishing materials that meet modern environmental requirements is important. Structural elements of buildings have dominated for many centuries and have broad prospects for use in modern capital construction: they have high strength and rigidity; they are reliable and durable and have a low installation weight. In particular, in a number of Western countries, high-rise buildings are already being built using a frame made of glued wooden structures. Despite the natural symmetry of coniferous woods structure, its non-standard tracheids are the main reason for the variability of its mechanical properties. In addition, when calculating glued reinforced structures, it is necessary to take into account the so-called "scale effect" when calculating the bent glued wooden elements. The applied methods for the calculation of "low" reinforced beams sometimes give an error in the calculation of "high" beams. In this paper, the definition of a more rational method of calculating the "high" beams with symmetrical reinforcement and comparison of options for reinforcing such beams are performed
