Universal design characteristics of compressed concrete at different strain rates

This article is aimed at predicting the defining physical and mechanical characteristics of compressed concrete, which are necessary for the calculation of reinforced concrete elements under the action of any intensity loads. The methodology for determining these characteristics is based on the well-known law of conservation of potential energy of ultimate deformation (destruction) of concrete regardless of its strain rate. The interdependence of strength and deformation characteristics of compressed concrete at different strain rates is proposed to be predicted using a complex universal characteristic - the elastic-plastic coefficient of concrete. A function is proposed that allows predicting the probable variability of this characteristic for different classes of concrete in the widest range of its strain rates.
