The article describes the design and technological solutions for the nodal joints of wooden structures with local wood modification. The results of numerical and experimental studies on the bearing capacity and deformability of such joints are presented. Numerical studies were carried out using the Ansys program. As a modifying composition, a compound based on dimethacrylic polyester with the addition of a hardener and a curing initiator is proposed. Experimental studies were carried out using a modernized hydraulic bench for testing beam structures made of wood. The results obtained allow us to speak about an increase in the bearing capacity of wood in nodal joints due to modification by 29–30%. The possibility of local wood modification has been proved. Design solutions for aluminum connectors are given, which allow modifying wood in production conditions and on the construction site. The setting for the local modification of the wood of the contact zones, consisting of a vacuum pump, a compressor and a container for modification, is considered. Based on the studies carried out, it can be argued that it is important to increase the physical, mechanical and operational characteristics of wood due to local modification. Further research is aimed at improving the technology of modification and design solutions for connections.
