Vibrì is MoHo’s new software for vibration analysis.
In recent times, the problem of vibrations that can affect people in buildings and potentially damage structures has become a topic of great interest. There are many sources of vibration: trains, traffic, construction sites, industrial machinery, refrigeration equipment, facilities for sports and recreational use, and so on. Legislation has become more specialized, and there has been a growing awareness of the quantification and mitigation of vibrations, both by those who produce them and by those who experience them.
To analyze this type of data, MoHo has produced two new software:
- Vibrì for Humans
- Vibrì for Structures
If you cannot deal with the vibration problem on your own, contact us. We can analyze it for you!
What is it?
Vibrì for Humans is MoHo’s software for the analysis of vibrations affecting people in different types of buildings (residential, industrial, business, educational, medical). Watch the tutorial on our YouTube channel.
Vibrì for Structures is MoHo’s software for the assessment of (non-seismic) vibrations potentially damaging to structures, according to UNI-9916 and other European standards (DIN-4150, CIRCULAIRE 86, etc.).
What is it meant for?
Vibrì for Humans and Vibrì for Structures work with data acquired with MoHo instruments (TROMINO®, SURICAT, SOILSPY), but also with text files and general formats from other instruments.
The analysis of vibrations affecting people involves filtering the data (typically in acceleration) according to the human sensitivity curve. Statistical evaluations are then made on these data to argue whether or not the vibrations perceived at the site are tolerable. Disturbance threshold values vary both in relation to the activity at the site of interest and the time of day.
If the analysis is to be carried out to evaluate the expected vibration level in a structure that does not yet exist, Vibrì for Humans can be used in combination with SWING, MoHo’s software for predicting the vibration level in structures yet to be built.
Vibrì for Structures analyzes (non-seismic) vibrations according to their potential harmfulness to structures. The analysis is typically conducted on velocity data (thus acquired by velocimeters or geophones/seismometers) and consists of extracting epochs of maximum amplitude that will then be analyzed at the spectral level. The pairs (maximum amplitude, relative peak frequency) are then compared with damage threshold values, which are also frequency-dependent.
The software can be complemented with threshold values from regulations and standards other than those mentioned: please contact us if necessary.
