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.
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.
Dams monitoring
There are different kinds of dams and each type needs a specific monitoring system. We can offer all the instrumentation to monitor them.
