Reinforcement of brick partitions of buildings located in seismic areas with composite materials based on carbon fibers

Abstract

Brick masonry is one of the most commonly used materials for creating internal partitions of buildings, including those located in seismic areas. The codes of a number of countries, including Russia, prescribe design requirements for strengthening partitions with external discrete steel reinforcement. At the same time, this solution is both labor-intensive in the production of works, and increases the seismic load on the partition (increasing the mass of the partition). This article explores the option of replacing the steel external reinforcement of partitions with composite roll materials – grids and tapes on an epoxy basis. The analysis of the strength values obtained in the course of experimental studies is carried out, and the result of calculations of the load-bearing capacity of characteristic partitions of real buildings with and without external reinforcement is given.
