A certain sequence for calculating the deflections of such elements is proposed. The options for beam loading to establish the ratio of the maximum moment to the deflection are presented. A theoretical analysis was carried out and the results obtained while modeling the operation of a wooden beam of rectangular cross-section based on Moment Curvature graphs were described in this article. The dependences of the simultaneous achievement of the limit states for the first (in terms of bearing capacity) and the second (in terms of deflections) groups of limit states depending on the ratio of the geometric dimensions of solid and glued wooden beams were established. © 2023 The Authors.

Introduction Wood is one of the most important materials on our planet due to its natural origin (Green and Kretschmann (1992), Da Silva and Kyriakides (2007), Yasniy et al. (2022), Homon et al. (2023)). It is often used in various industries (Bosak et al. (2021)). One of these industries is construction. Wood is used for finishing buildings and structures, as well as load-bearing elements (Nsouami et al. (2022), Zhou et al. (2018), Gomon et al. (2022), Mascia et al. (2018)). Wood can be used in floors, Galicki and Czech (2005), roofs, walls, pile foundations and more.
