AbstractRegularities of changes in the stress-strain state of reinforced concrete in the process of testing for four-point bending have been studied. The change in characteristics of the electric response to an impact action in the process of a sequential increase in the external load has been analyzed. Regularities in the relation between parameters of the electric response to the impact action and stages of the stress-strain state of reinforced beams in the process of bending have been revealed. Criteria of determining stages of reinforced beam destruction by parameters of the electric response are proposed.
