Tromino for engineering
Supporting engineers and architects in the design, monitoring, modelling and retrofitting of structures…
TROMINO®, originally conceived for the dynamic characterization of subsoils, has been increasingly used for the operational modal analysis of structures to such an extent that this has become its primary application over the years. TROMINO® has been used on the most iconic structures worldwide, such as the Eiffel tower, the Golden Gate bridge in San Francisco, the Shanghai tower, the leaning tower of Pisa and many more.
The exclusive radio communication system among several units, the total lack of cables and external batteries, the light weights and small sizes, make working with networks of TROMINO® a unique experience.
What is it?
TROMINO® is a small (1 dm3, < 1 kg) all-in-one instrument, equipped with:
- 3 velocimetric channels (adjustable dynamic range)
- 3 accelerometric channels
- 1 analog channel
- GPS receiver
- built-in radio transmitter/receiver (for synchronization among different units)
- radio triggering system (for MASW surveys and similar)
TROMINO® works in the [0.1, 1024] Hz range and is powered by 2 AA (1.5 V) batteries only!
What is it meant for?
With a single TROMINO®
Modal frequencies and damping of structures
With several (min. 2) TROMINO® units
Full operational modal analysis (modal frequencies, shape and damping) of structures.
Validation of structural models
TROMINO® provides the key parameters to tune and constrain numerical models of structures.
Vibration analysis and monitoring
Analysis of strong vibrations, potentially damaging for the structures, according to European norms (UNI9916, DIN4150).
Detection of soil and structure resonance frequencies, soil-structure interaction (rocking).
GRILLA is the software tool to archive, organize, view and analyze the recordings of TROMINO®.
GRILLA is interactive, user-friendly and produces automatic reports.
TROMINO® is internationally patented.
