ABSTRACT
ABSTRACT In the article, three types of serious errors in the international norms of concrete and reinforced concrete caused by the violation of the Eurocode rules were identified and investigated. Two types of errors are associated with loss of instant non-linearity of concrete. This is an erroneous replacement of elastoplastic deformation by deformations of linear creep of concrete and substitution of the process of continuous loading of the structure by a jump from the elastic stage to the plastic hinge, bypassing the elastoplastic stage. The third type of error was caused by the erroneous copying of the principle of the linear superposition of Boltzmann as the principle of superposition in the creep of concrete.
