Приводятся, как традиционные, так и новые методы усиления с применением композитных сеток (ФАП) из стекловолокон и углеволокон. Анализируются результаты экспериментальных исследований армированных и неармированных каменных образцов при воздействии сжимающих сил и обсуждаются механизмы их разрушения. Также рассматриваются результаты численных исследований армированных каменных элементов при воздействии внецентренно приложенных сжимающих сил. Используется система усиления композитными материалами Fibre Reinforced Polymers (FRP), в рамках которой, в виде адгезива, используются эпоксидные клея. Проводится анализ распределения главных сжимающих напряжений действующих в армированных сетками образцах различного сечения (квадратного, прямоугольного и круглого) и определяются зоны концентрации этих напряжений. </p></abstract><trans-abstract xml:lang="en"><p>The paper analyzes the effectiveness of strengthening techniques for masonry elements under central compression and compression combined with bending. Traditional and new strengthening techniques using composite carbon and fiberglass mesh (FRP) are given. The results of experimental investigations of reinforced and unreinforced masonry specimens under compressive loads are analyzed and their failure mechanisms are discussed. Furthermore, it discusses results of numerical analysis of reinforced masonry elements under eccentrically applied compressive loads. The fibre-reinforced polymer strengthening system is used, within which, epoxy adhesive is applied. The distribution of main compressive stresses in reinforced specimens with different sections (square, rectangular and circular) are analyzed and these stress concentration zones are determined.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>каменные элементы</kwd><kwd>усиление</kwd><kwd>композитные материалы (ФАП)</kwd></kwd-group><kwd-group xml:lang="en"><kwd>masonry elements</kwd><kwd>strengthening</kwd><kwd>composite mesh (FRP)</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Masia MJ, Shrive NG.
