Исследовались значения начальной прочности при сдвиге (прочности касательного сцепления) и предельные значения прочности при сдвиге. Испытания каменных кладок выполнялись согласно СТБ EN 1052-3 при одновременном действии сжимающих и сдвигающих усилий. В зависимости от уровня обжатия разрушение каменных кладок происходило вследствие сдвига по границе кладочного изделия и растворного шва и раздробления перегородок между пустотами блоков. Установлено, что предельные значения прочности кладки при сдвиге, приведенные в нормах по проектированию каменных конструкций, существенно превышают экспериментальные значения. Указано на необходимость корректировки положения нормативных документов, касающиеся предельных значений прочности при сдвиге каменных кладок из поризованных керамических блоков.</p></abstract><trans-abstract xml:lang="en"><p>The article presents the results of experimental studies of shear strength in the plane of horizontal mortar joints of masonry from porous ceramic blocks. The initial shear strength values were investigated (strength of tangential adhesion), as well as the ultimate shear strength values. Experiments with masonry were carried out in accordance with STB EN 1052-3 with simultaneous action of compressive and shear forces. Depending on the compression level, the destruction of masonry occurred due to a shift along the border of the masonry product and the mortar joint and fragmentation of the partitions between the voids of the blocks. It has been established that the limiting values of masonry shear strength, given in the standards for the design of stone structures, significantly exceed the experimental values. The need to correct the provisions of regulatory documents regarding the ultimate values of shear strength of masonry from porous ceramic blocks is indicated.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>каменная кладка</kwd><kwd>керамические поризованные блоки</kwd><kwd>неперевязанное сечение</kwd><kwd>прочность при сдвиге</kwd></kwd-group><kwd-group xml:lang="en"><kwd>masonry</kwd><kwd>ceramic porous blocks</kwd><kwd>unbonded section</kwd><kwd>shear strength</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">Mann W., Műller H.
