The laboratory uses data acquisition equipment, vibration sensors, and inertial measurement units (IMUs) to measure structural responses. These instruments support experimental modal analysis, vibration-based structural health monitoring, and damage detection research.
The lab has a commercial NI-DAQ system and a low-cost, solar-powered in-house DAQ. The in-house unit uses USB hubs, a voltage regulator, a solar charge controller and a 12 V 20 Ah LiFePO₄ battery, which makes it suitable for field monitoring.
Sensors available:
Accelerometers: Uni-axial and tri-axial piezoelectric accelerometers (used with the NI-DAQ), and Epson accelerometers
Vibration sensor: Epson M-A542VR1
IMU: Epson M-G552PR
The laboratory setup is used for experimental investigations related to Bridge Weigh-In-Motion (BWIM), which estimates vehicle loads and axle weights from measured structural responses. It supports research on bridge monitoring, load identification, and structural condition assessment.
