    Absatrct. During the operation of wooden structures made of solid wood, it is often necessary to restore and strengthen them. The analysis of various options for strengthening the bent structures showed that the simplest, and at the same time effective way is to strengthen by increasing the cross-section. The composite cross-section is formed due to the use of connecting links, while it is advisable to use discrete mechanical links of the nagel type as part of the reinforcement of the operated structures. In the course of the evolutionary development of such connections, a steel rod of a twisted cross-section shape was developed. The variant of ties considered has a number of advantages in comparison with traditional types of ties, which determines the feasibility of their use in the framework of strengthening the bent structures. Theoretical studies of a bent beam of composite cross-section formed using twisted cross-shaped rods are presented. The results of numerical studies of the stress-strain state of the structure carried out in the ANSYS WorkBench software package are presented. The results obtained were analyzed and compared with experimental studies of full-scale samples of a similar design solution. The data obtained showed that the proposed types of twisted cross-shaped rods provide the necessary strength and rigidity of the structures reinforced with them.
    Key words: bendable structures, steel twisted cross-shaped rod, strengthening of wooden structures, wooden beam, increasing the cross-section.
