The article is devoted to the study of one of the main properties of concrete - nonlinear creep. Methods for determining the effect of nonlinear creep on the stress-strain state of reinforced concrete structures operating without cracks in a tensile zone are relatively well developed. To a lesser extent, the methods of nonlinear creep calculation for cracked structures have been studied, especially when taking into account the gradual application of the load over time and the redistribution of stresses along the height of the compressed zone of sections. To solve this problem, the article discusses the features of the application of the step version of the method of elastic solutions for reinforced concrete bar structures with reinforcement in the compressed and stretched zones of the section under bending or eccentric compression. The purpose of the article is to determine the stress-strain state of reinforced concrete beam caused by nonlinear creep under instantaneous and step loads, compare it with the experiments of other scientists, and analyze the results obtained.
