Abstract

The authors of the article investigate new design solutions for the restoration of damaged masonry vaults and arches. The article presents the results of experimental studies of the deformability of reinforced and unreinforced masonry arches on lime-sand solutions during normal operation with a fracture factor (horizontal and vertical movement of the support). During the study numerical and physical experiments were carried out. The article also presents the results of observations of the basement floor of the building of the Kazan Hotel on Bauman Street, Kazan, Russia. The study allowed authors to determine the deformation and crack formation of masonry arches. The experiment included a test of an unreinforced arch, until damage was obtained when a support movement occurred. At the second stage of the experiment, the damaged arch was strengthened by the developed method, and its further testing was carried out. The study allowed authors to determine the vertical displacement of the arch before and after amplification. According to the test results, one can make an assumption about the change in the deformability and destruction of the reinforced masonry arch. The reason for this may be a halt in the development of cracks that have appeared and a change in vertical displacements.
