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.
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.
Solutions, instruments and software for seismology, geophysics and vibrometry
In compliance with the 22th March DCPM, the SARA Electronic Instrument srl laboratori will remain closed until the new decree or subsequent ordinance. We are still supporting our client and giving services in smart-working mode through digital communication. the seismic monitoring and data recovering service with our client remain active.
