There are different kinds of dams and each type needs a specific monitoring system. We can offer all the instrumentation to monitor them.
HVSR
The HVSR, or Nakamura method, allows to highlight the possible resonance frequency of a soil. This value is calculated by making the ratio between the average of the horizontal spectra on the vertical spectrum (H / V) of the natural vibrational signal.
Modal analysis
In structural engineering, modal analysis uses the overall mass and stiffness of a structure to find the various periods at which it will naturally resonate. These periods of vibration are very important to note in earthquake engineering.
