The study of the stress–strain state of a bent rigid joint was carried out by solving a volumetric problem of the theory of elasticity using a software package based on the finite element method, which makes it possible to take into account the anisotropy of the mechanical properties of wood, the physical nonlinearity of materials, and the contact failure between the element surfaces. Experimental studies were carried out by the method of four-point static loading of a full-size specimen of a rigid joint, which in its geometric parameters and material properties corresponded to the FE-model. As a result of the performed studies, it was found that the height of the compression joint zone depends on the strain capacity of the embedded parts connection, the level of stresses in the connecting plates and the elastic characteristics of timber. The strain capacity of the embedded parts connection in the compressive zone is greater than the strain capacity of the embedded parts connection in the tensile zone. The distribution of stresses along the length of the inclined reinforcing bars is characterized by great unevenness. The coefficient of non-uniformity of normal stresses between the inclined reinforcing bars of the compressive zone connection is in the range of 0.61 ÷ 0.38, and in the tensile zone—0.7 ÷ 0.51.
