Abstract

The main regularities of the relation between the actual destruction of reinforced concrete samples under uniaxial compression and the characteristics of fracture mechanics and indirect physical parameters are investigated in this work. Studies of samples with different types of reinforcement and different strength of concrete are carried out. Destruction stages of reinforced concrete under uniaxial compression are established and the corresponding diagnostic criteria of evaluation are proposed. The evaluation procedure is based on measuring the electric response to a weak mechanical impact. Measurements of the electric response are carried out periodically during a gradual increase of external load. Analysis of signals in the time and frequency domain is the basis of the algorithm used for evaluating the degradation processes of reinforced concrete under uniaxial compression.
