Theoretical and experimental studies of the stress-strain state with a short pulling force acting on concrete smooth steel rods with acrylic adhesives were carried out by such scientists as L.N. Shutenko, M.S. Zolotov, B.Yu. Pagi, etc. However, it should be noted that when performing these experimental studies ordinary acrylic adhesive was used. The purpose of the experimental studies was to determine the short-term strength of anchor bolted joints on acrylic adhesives using various modifiers and the depths of bolt insertion. As glue in the manufacture of prototypes of anchor bolted joints, a modified acrylic composition was used. If we accept the strength of the ZnO seal as 100 %, then the strength of the ground mica and methacrylic acid seals differ by 0.35 MPa and 3.5 %, respectively. The results of experiments to determine the strength of anchor bolted joints are systematized depending on the diameter of the anchors and the depth of their embedment in concrete. Based on our studies and analysis of experiments by other researchers, it is recommended that anchoring bolted joints to a depth of l = 8d s .
