| Sumario: | Заглавие с экрана It is showed the results of reinforcement-concrete contact quality influence on the parametres of an electric response at elastic shock excitation. The researches carried out on a reinforced concrete laboratory models. Models represented as a samples of heavy concrete at a size of 100х100х100 mm with a metal stick inside in the center with a diameter of 10 mm and length of 120 mm. Artificial degradation of contact quality was reached by greasing a reinforcing stick with an oil. The methodics of reinforcement-concrete contact adhesive strength determination in the studied models reinforced concrete models is offered. It is established that contact strength changing does not lead to significant change of signal amplitude, but conducts to appreciable change spectral peaks ratio of electric responses. |
