This article is devoted to the peculiarities of calculating deformability modifications of the timber elements on mechanical linkages. Here we analyze in detail the method of V.M. Kochenov used in the design standards of the Russian Federation. This method allows accurately determining the number of links that are able to resist the shear force in the linkage, however, this method does not include analyzing of shear deformation in modifications. And it is an important disadvantage. In this article the author considers another approach, based on the idea of determining the shear deformation of the mechanical linkage, installed in the connection. In order to calculate the shear deformations of the connections in the linkage it is necessary to conduct a preliminary analysis of the construction, to establish the type of connection and the thickness of the connected elements, to determine the number of slice planes, the number of established connections and the load level on the connection. After determining these values, structural analysis design is performed. This article describes in detail the theoretical aspects of this method, used assumptions and limitations. A test case is considered for validation of the considered methods.
