On some approaches to solving relaxation problems of concrete
Abstract
The difficulty that accompanies the application of the creep theory in construction practice, according to the authors, is the decomposition of the deformation properties of concrete. It has developed historically. In 1660, R. Hooke formulated a law that defines the relationship between stress and deformation of an elastic body. For the first time, A. Consider drew attention to the inelastic properties of concrete (publication in 1905), that is, 245 years later. Since that time, it is possible to count the study of creep, which was conducted in parallel with the study of the elasticity of concrete and, in connection with the priority of the time of research on elasticity, creep has become an applied role. Both directions had their own empirical dependencies, which were not connected with each other in any way. This led to the fact that the dependences obtained from experiments that were carried out under different conditions, the division of the experimental values of deformations into elastic and inelastic ones were carried out in different ways. This paper shows that the generality property of the aging function makes it possible to avoid this decomposition.
