Instruments for Seismic and Vibrational Monitoring of Structures.
Acquiring key parameters of the motion of structures and soil during earthquakes or other excitations stress is critical in Structural Health Monitoring and seismic hazard studies.
SURICAT is the cost-effective strong-motion accelerometer and velocimeter designed for the permanent or long-term monitoring of structures: adequately accurate to provide information of engineering interest, and inexpensive enough to be used in extended networks.
Suricat can also be used as a stand-alone instrument. The display makes its functioning intuitive. The complete absence of cables and the integrated power supply make its use simple and straightforward even for ultra-rapid surveys.
What is it?
SURICAT is a GPS-equipped, three-component digital accelerometer and velocimeter designed for permanent or extended installations on structures. Thanks to the display, which allows viewing and access to all settings and data-saving functions, SURICAT can also work in stand-alone mode. The absence of cables makes it particularly suitable for quick surveys at different sites.
In distributed applications, SURICAT transmits data via Bluetooth connection (Suricat App for Android) or network cable.
In the absence of a network connection, SURICAT saves data in internal memory until the network becomes active again.
SURICAT is powered by an internal lithium battery that provides a runtime of several hours. The internal memory card can store data for many days.
What is it meant for?
SURICAT acquires acceleration and velocity values over time at the installation site. The GPS module provides absolute time.
SURICAT can be used for:
- operational modal analysis (OMA) and experimental modal analysis (EMA) of structures
- analysis of vibration nuisant to people. Vibrì for Humans software is optimized for SURICAT data analysis
- analysis of vibration potentially damaging for structures. Vibrì for Structures software is optimized for SURICAT data analysis
- monitoring the health of structures and infrastructures (Structural Health Monitoring, SHM)
- analyzing the response of structures to earthquake or other dynamic stresses
- recording peak acceleration values or other spectral parameters for ground Shakemaps
- dynamic soil analysis (H/V)
