    Abstract. The use of anchor fasteners in multilayer enclosing structures is considered. A model has been developed that takes into account the influence of strength parameters of materials of multilayer enclosing structures, in particular, mortar and stone (brick) on the bearing capacity of anchor devices, when they are removed and displaced in the structure. A computational complex is proposed that makes it possible to determine the resistance of masonry in its stressed state, characterized by flexural stretching and axial stretching, taking into account the influence of a number of factors. The results of tests of the adhesive strength of anchors in brickwork carried out on samples of bricks of various types - silicate and ceramic - are presented. The permissible tangential stresses in the mortar seam of the masonry during the extraction of the anchor are determined. The work of anchors intended for use in solid or hollow masonry, as well as for connecting layers in multilayer walls, is considered. Recommendations for the installation of anchors in the masonry walls are given. Analysis of the test results revealed a number of problems that exist in the design of fasteners in building structures and, as a result, during construction control.
