Abstract
By present time significant experimental and theoretical material on concrete creep has been accumulated. At the same time, the known approaches to calculation of concrete and reinforced concrete structures with regard to creep are oriented mainly to solving problems with relatively simple geometry of the product. Moreover, there are no mechanic-mathematical models of hereditary type oriented to the finite-element method.The concept of modelling of long-term deformation of reinforced concrete structures in a three-dimensional statement, based on the use of the integral deformation modulus of concrete, does not allow one to carry out designing considering the technological prehistory. Therefore, the problem of developing a finite-element algorithm and corresponding software allowing the modelling of the volumetric stress-strain state of large-span prestressed reinforced concrete structures within the framework of the theory of hereditary aging is relevant.
