Abstract

The proposed work identified and analyzed the errors in the theory of viscoelasticity of concrete in international norms for concrete and reinforced concrete, new equations of the theory of creep of concrete, taking into account the instant nonlinearity, nonlinear creep and inertial properties of concrete. The results of the study are brought to the charts and tables, convenient for use by ordinary designers. The article was written in accordance with the recommendations of the round table, held at RUDN University on June 9, 2016 under the guid- ance of Doctor of Technical Sciences, prof. S.N. Krivoshapko.
