This paper presents the results of the calculation of reinforced concrete columns strengthened under the action of the initial load. Most of the reinforced concrete structures are damaged by various factors and require restoration and strengthening. However, most of these structures are operated under a certain level of load. During the operation of the building, complete unloading of the structure could be quite difficult, and in some cases even impossible to perform. Such loads could include the own weight of the structure, flooring, technological equipment that cannot be dismantled. Therefore, the structure can only be unloaded to a certain level. When strengthening reinforced concrete elements, it is necessary to identify the real stress-strain state of the structures in the loaded state. Therefore, studies of eccentrically compressed reinforced concrete structures, strengthened with modern materials under certain load level, are relevant. Nowadays, there is the great number of strengthening methods for such structures. One of such modern methods is gluing in stretched zone the carbon tapes. In this work SikaCarbodur S512 carbon tapes were used. Theoretical calculation was performed for non-centrally compressed reinforced concrete columns with dimensions 180 × 140 × 2200 mm. The eccentricity was 150 mm. Comparison between results of theoretical calculation taking into account the operating load and previous experimental studies is presented. Deviations of experimental and theoretical data are established. As a result, the proposed method, which is based on European standards, allows calculations of such structures with satisfactory convergence.
