The method of numerical modeling of the stress-strain state of a continuous reinforced concrete beam in Ansys Mechanical is described. A comparative analysis of the obtained results with the experimental data of the authors. The study revealed the redistribution of internal forces due to the appearance of a conditional "plastic hinge" over the middle support and under concentrated forces and the influence of the studied factors on them. A mathematical model of the relative increase of bending moments under concentrated force in spans after the appearance of a "plastic hinge" over the middle support is presented. Comparative analysis of experimental data of strength, crack resistance and deformability with the results of theoretical calculations using software packages LIRA-Soft, ANSYS Mechanical and deformation model implemented in MATLAB showed satisfactory convergence (coefficient of variation in the range from 9 to 15 %) [ABSTRACT FROM AUTHOR] |
