The presented approach has been studied and discussed in this paper on the background of the numerical and experimental data. As it was expected, the proposed strengthening method is efficient and promising in case of the \u201cimmediate\u201d repairs of critical members with cracks. The manufacturing process of specimens and test methodology as well as numerical approach to calculate SIFs for various reinforcements of steel specimens are presented. For this purpose, the Extended Finite Element Method was involved and described.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title content-type=\"abstract-subheading\">Findings<\/jats:title>\n<jats:p>The main mechanism of fatigue crack growth retardation is associated with local \u0394<jats:italic>K<\/jats:italic> reduction due to CFRP patches; any type of reinforcement results in an increase in <jats:italic>a<\/jats:italic><jats:sub><jats:italic>f<\/jats:italic><\/jats:sub> and a significant decrease in SIF values. The beach-marking method is described as a good, reliable and comprehensive method to capture the crack propagation in structures consisting of various materials and could be applied successfully for mixed mode testing.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title content-type=\"abstract-subheading\">Originality\/value<\/jats:title>\n<jats:p>A detailed experimental-numerical approach for fatigue crack growth in long-term operated structures made of steel is presented.
