This article presents the main recommendations for the construction of nodes of solid-wood structures. The basic scheme of the rigid junction of the meridional edges is considered. Based on the results of tests and calculations, conclusions are drawn on the possibility of improving this node. Some recommendations for strengthening the node without increasing the metal capacity of the structure are presented. Several schemes for improving the welded structures are shown. Conclusions are drawn on the possibility of implementing the examples given in the designed structures.

This article presents the main achievements of the foreign engineering school in the field of research and application of composite materials to reinforce wooden structures. Some options for reinforcing glued and solid wooden elements are considered. The results of tests of reinforced wooden structures are analyzed. Errors made during the manufacture of samples and the course of testing are noted. Conclusions are drawn on the basis of the conducted research.
