    Abstract. In connection with the increase in the volume of wooden construction in Russia, the search for effective methods of strengthening and increasing the bearing capacity of elements made on the basis of wood is very relevant. The analysis of the known options of strengthening of wooden designs has shown that increase in cross section is the simplest, and at the same time effective way. Compound section is formed due to the use of connecting communicators, at the same time it is expedient to use discrete mechanical dowel type communicators within strengthening the operated designs. Authors developed and investigated steel twisted crosswise cores which advantages can be used for strengthening wooden structures. The constructive solution of the most characteristic and common variants of strengthening of the operated wooden structures executed with steel cylindrical dowels (basic variant) and the offered types of communicators is developed: strengthening of the floor beam; restoration of the basic knot of a beam struck with rotting; increase in the bearing ability of the compressed strut during reconstruction of the production building (an extension of additional span). The comparative technical and economic analysis of the considered ways of strengthening which has confirmed the expediency of use of twisted steel crosswise cores when strengthening wooden elements and structures.
    Key words: strengthening of wooden structures, variants of strengthening , twisted crosswise core, ties of dowel type, technical and economic analysis.
