Abstract
A finite element algorithm and corresponding software have been developed that allow modeling the volumetric stress-strain state of large-span prestressed reinforced concrete structures within the framework of the theory of hereditary aging. The construction of an algorithm for calculating the hereditary function of concrete and the development of an appropriate finite element program have been studied. In contrast to the generally accepted practice of modeling long-term deformation, based on the use of the integral modulus of concrete deformation, the proposed approach allows the calculation of large-span reinforced concrete structures, taking into account the history of quasi-static variable loading.
