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.
To simplify the use of our software and instruments, to explain the features inside the software, we have created a YouTube channel, where we will upload Tutorials and presentations of our products.
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.
