Defining the Parameters of Loading of Concrete Bridges Superstructures Basing on the Level of Vibroacoustic Emission Signals

The technique and experimental equipment for remote monitoring of concrete bridge superstructures by vibroacoustic emission signals method was developed. The transducers are mounted on concrete beams for measuring the oscillation energy of moving vehicles within the two frequency ranges. Deflections of beams are measured by low-frequency vibrations and the intensity of degradation processes in the beams is determined by high-frequency vibrations. It is proposed to use the ratio of vibrations intensity indicators within the specified frequency ranges for the diagnostics of the technical state of reinforced concrete beams of superstructures and forecasting residual operational life. The industrial testing of experimental equipment for different traffic volume was held.
