The results obtained using standard and improved (modified) calculation methods for load distribution on fasteners and joints strength are analyzed on the examples of four types of multiple-row metal-composite joints with cover plates of various thickness and various diameters of fasteners. A modified technique based on the Nuismer criterion is used to determine the load-bearing capacity. It was determined that for all joints the difference between the calculation results and the experiment is 14 - 26% using this criterion. It’s desirable to use a modified scheme of the Nuismer criterion to improve a calculation convergence of the load-bearing capacity with experimental data. In this case, the maximum difference between the calculation results and the experimental data for the considered joints was 12.9%.
