Abstract
Abstract Based on the analysis of approaches to reinforcing the brick masonry structures, the advantages of carbon fiber as a reinforcing component are presented. Methods for calculating brick structures reinforced with carbon fiber under central and eccentric compression are proposed. These methods allow determining the longitudinal force taking into account the calculated compressive resistance of the masonry, the masonry working conditions and the influence of long-term load, as well as the coefficient of the masonry surface reinforcement at the reinforced wall. The schemes of strengthening the wall with vertical canvases and at the same time vertical and horizontal carbon fiber canvases are considered. Depending on the direction of the eccentricity of the load application, methods for calculating the strength of reinforced masonry under the action of a moment in the masonry plane and from the wall are developed. The ultimate deformations of carbon fiber are estimated taking into account possible options for the destruction of masonry reinforcing elements.
