As a result of exposure to alternating temperatures, there occurs concrete degradation. Its strength and limiting relative deformations are reduced under axialcompression ε_b0. In the design standards ε_b0 is accepted as average values, which does not allow assessing the level of reliability of the bearing capacity of eccentrically compressed reinforced concrete elements. The effects of alternating freezing and thawing of concrete will reduce the level of load-bearing capacity. Using the methods of mathematical statistics and diagrammatic calculation for compressed reinforced concrete elements, there has been made an assessment of the effect of variability inthe strength and deformation characteristics of concrete under the influence of alternating temperatures on their bearing capacity.
