【 摘 要 】

The numerical analysis results of arched constructions are considered taking into account creep of the material. A typical building material substantially exhibiting creep under long-term loading is concrete. As a basic model of concrete creep, a model of viscoelastic material was selected. The model was verified and calibrated on the experimental studies basis of concrete creep and in accordance with the requirements of regulatory documents. Numerical modeling of arches was carried out in the software environment of SIMULIA Abaqus.
