Abstract

The substantiation of the computational rheological model of the material for use in computer calcula­tions of concrete and reinforced concrete structures of arbitrary complexity, taking into account the creep of con­crete, with possible changes in the intensity of the current load over time, is presented. The computational model is based on the Maxwell-Weichert generalized model of the viscoelastic material. The model was verified on the basis of experimental data and requirements of regulatory documents for the calculations of concrete and rein­forced concrete structures, taking into account the creep of the material. Verification of the computational model and numerical calculations using the selected computational model were performed in the SIMULIA Abaqus software environment.
