Abstract. The analysis of methods for calculation of anchorages with the use of mechanical and chemical anchors according to domestic and European technical documents is presented. The possibility to use the methodology for calculating anchors of inserts pre-installed in concrete by domestic regulations is considered. The results of calculation according to domestic regulations are compared with the results of calculations of anchors post-installed in the concrete base by the European normative document. The accuracy of the above calculation methods is compared with the experimental data obtained by the authors. The analysis of the reliability of available formulas of domestic and foreign regulatory documents is conducted by methods of statistical experiment. The conclusion about the difference in the accuracy of the compared methods is made and new dependences for the calculation of anchors according to domestic norms are proposed. The need for adjusting the national requirements for the assessment of the bearing capacity of anchorages is shown.
Key words: anchorage, mechanical and glue bonded anchors, accuracy factor of calculation technique, bearing capacity, constructive reliability. - REFERENCES
