A stress-strain history in the material of real concrete structures is usually unknown. An effect of concrete degradation is analyzed to describe how the initial degradation parameter can describe the stress-strain history. The idea is to introduce the initial damage of the structure by the degradation parameter to calculate the internal variables of the constitutive model. Six numerical examples are proposed to verify the methodology for various loading conditions. Based on the obtained results, it was shown that unknown stress-strain history could be successfully represented using the original material parameters and the initial degradation of the concrete. The stress-strain behavior of the damaged concrete is successfully simulated and essential for the structural analysis of civil engineering structures.
