Abstract
The paper presents the strength analysis of bending reinforced concrete elements in the Matlab support package. The versatility of the deformation model is its ability to conduct control tests, for example, verification of structural analysis at the design stage. Based on the standard stress-strain state diagrams of materials and iteration procedures, two independent nonlinear analyses are suggested. One of the main accepted conditions is that iteration procedures occur at the elastic behavior of the member. Iteration procedures determine the maximum member curvature and its deformation. The strength criterion is theoretically calculated deformation, which must not exceed permissible values specified in construction codes and regulations. Calculation algorithms are given in flowcharts. In conclusion, the results of experimental data are presented.
