Strength and Deformability of a Complex-Stressed Reinforced Concrete Element Based on the Plasticity Theory of G. A. Geniev

In connection with ensuring the necessary reliability in the operation of both the building and the structure as a whole and its elements, as well as the need to prevent progressive collapse under special actions, it is important to develop effective calculation models for analyzing the strength and deformability of the most used structural material—concrete and reinforced concrete. The article summarizes the working prerequisites and hypotheses necessary for the construction of general physical relationships (relationships between stresses and deformations) of a complex-stressed reinforced concrete element. The criteria for assessing the strength and deformability of reinforced concrete under triaxial and biaxial stress are presented. When constructing the calculation model of the resistance of this composite material, the physical non-linear work of concrete was taken into account based on the theory of plasticity by G. A. Geniev, as well as its anisotropy in the form of reinforcement coefficients and other factors.
