    Abstract. The operation of external reinforcement systems based on carbon fibers when strengthening normal and inclined sections of bending reinforced concrete elements depends largely on the anchoring to the body of the reinforced structure. In addition to adhesion, one of the options for ensuring the required level of anchoring of external reinforcement is the installation of anchoring elements, including those based on carbon fibers. This article discusses the calculation of anchors based on carbon fibres used in the arrangement of the external reinforcement system. Two principles of anchor arrangement operation are highlighted: for shear and for pull-out. Separate design provisions have been developed for each, taking into account the parameters of anchoring elements and the nature of the destruction obtained during experimental studies. The proposed calculation methods are based on experimental studies of both bending elements reinforced by external reinforcement systems and directly anchoring elements. In addition, the development of these methods takes into account the provisions available in the regulatory documents on the calculation of anchors and composite materials.
    Key words: composite anchor, carbon fiber, external reinforcing system, calculation.
