Features of modeling composite reinforced concrete structures taking into account the reduced shear modulus
Incoming article date: 29.12.2024The article discusses the features of modeling composite reinforced concrete beams from various (B25 and B65) concrete strength classes. The basic principles of the theory of composite rods were applied in the modeling process. The section of the reinforced concrete beam was divided by boundary layers with a reduced shear coefficient. The stresses and the nature of the distribution of deformations over the height of the beam section were evaluated before and after the introduction of a different number of boundary layers. During the extended analysis, options for introducing vertically arranged boundary layers along the length of the beam were considered. Based on the results obtained, it was possible to evaluate the specifics of the operation of bent structures with a different number of boundary layers.
