Man-made seismic effects, also known as human-induced seismicity, refer to minor earthquakes and tremors triggered by human activities that alter the stresses and strains on the Earth's crust. Although typically of low magnitude, these effects can cause vibrations that may gradually compromise the stability of structures, particularly in highway bridge structures where vibrations are induced by passing vehicles.

In highway bridges and other critical infrastructure, even slight vibrations can lead to structural damage over time. Monitoring these vibrations is crucial for taking proactive measures to prevent potential damage or instability. Resensys' wireless structural health monitoring solutions are designed to efficiently monitor and accurately quantify these human-induced seismic effects. The data gathered provides structure authorities with essential information to maintain structural integrity.

Key Parameters Monitored

Resensys’ system focuses on monitoring:
• Vibration (Single-axis or Tri-axial Acceleration: X, Y, Z axes)
• Ambient Temperature

The Resensys Wireless Vibration/Acceleration SenSpot™ sensors are designed for long-term, cost-effective, and accurate monitoring of vibrations on various structural members. Key features include:
‍
• Wireless Communication: No additional wiring required, reducing installation time and cost.
• Long Service Life: Ultra-low power usage with no need for battery replacement or maintenance during its lifespan.
• High Accuracy: Adjustable sampling interval, sensitivity threshold, and transmitting interval.
• Durability: Operates in extreme temperatures (-40°C to +65°C) and withstands harsh environmental conditions, including salty environments.
• Easy Installation: Lightweight and small, these sensors can be quickly installed on critical elements like piers, columns, abutments, and girders using adhesive or flange mounts.
