Prediction of the Nature of Deformation of Bent Slag Concrete Elements

In the modern world of information technology, computers are increasingly replacing our daily life. All real, field experiments and experiments replace computer modeling, as this often saves time. Numerous calculations, including reinforced concrete structures, are most conveniently performed using deformation diagrams of concrete and reinforcement. It is this method makes it possible to achieve similar results with field tests, the difficulty lies only in the fact that it is necessary to reduce many parameters of the equations. The aim of the work is to propose a simplified model of the deformation diagram of a bent slag concrete element, the use of which will help to exclude complex equilibrium experiments. The tables of the article show the values of the parametric points of the deformation diagram, the analysis of which shows the discrepancy between the experimental and theoretical values, therefore, the procedure for making adjustments to the formulas taking into account the dynamic movement of the main crack is given below. As a result of research and mathematical modeling of the bending element diagram, a model is proposed that is able to predict the nature of the specimen’s operation at any stage of loading, based on the highest load and the initial modulus of elasticity, which can be determined from the integral structural characteristic of concrete – compressive strength.
