| Popis: | Abstract Concrete creep is of great practical importance and is taken into account in calculation and design of structures. The article discusses various options for describing the theory of creep of concrete, which are divided into three main groups: the theory of an elastic-creeping body (hereditary theory of aging), the theory of elastic heredity (the theory of an visco-elastic body), and the theory of aging. The main advantages and disadvantages of their use are demonstrated depending on various conditions and processes. Collisions in the study of concrete creep are clearly visible when considering expressions for the creep measure, as well as creep and relaxation nuclei. Different scientists propose their own modification of expressions that reflect various features of the material, and which are often very different from each other. The authors of the article obtained the full creep equations of structural materials. |
