Testing a program for numerical analysis of the stress-strain state of reinforced concrete structures, taking into account the effect of rapidly increasing creep of concrete

As a mathematical tool for modeling the process of continuous deformation of reinforced con-crete structures, the finite element method was used in combination with a step-by-step proce-dure for numerical integration according to the time coordinate of the resulting operator-matrix equation. The program code is implemented on the basis of the Microsoft Visual Studio compu-ting platform and the Intel Parallel Studio XE compiler with the built-in Intel Visual Fortran Com-poser XE text editor. The processes of storing and processing working arrays are imple-mented in terms of sparse matrices. The descriptive graphics of the Matlab computer system were used to visualize the calculation results. All computational experiments were performed using the authorized Polygon complex. The objectives of the study include assessing the accuracy of the proposed methodology for analyzing the long-term deformation of reinforced concrete structures under various methods of external force action.
