Structural Health Monitoring

Structural Health Monitoring(SHM) is a critical aspect of maintaining the safety, integrity, and longevity of various civil structures, including historic buildings, bridges, tunnels, and large infrastructure. The purpose of SHM is to provide continuous, real-time data about the structural integrity of these assets, allowing for proactive maintenance and reducing the risk of catastrophic failures.

Why Structural Health Monitoring is Essential?

In civil engineering, maintaining the health of structures is vital for public safety and economic reasons. Structures like bridges, high-rise buildings, and tunnels are subject to various stresses over time, including environmental factors, load stresses, and material degradation. By implementing a robust SHM system, potential issues can be identified early, preventing costly repairs, minimizing downtime, and extending the lifespan of these critical assets.

Resensys' Structural Health Monitoring Solution

Resensys offers a comprehensive, cost-effective solution for SHM, leveraging advanced wireless technology to provide accurate, real-time data. Our SHM system is designed to monitor a wide range of parameters including strain, tilt, vibration, displacement, humidity, and temperature. Here’s how our solution stands out:
· Wireless Structural Health Monitoring: Resensys' wireless SenSpot™ sensors provide a hassle-free installation process with no wiring required, which reduces the time and cost associated with setting up monitoring systems. This wireless capability facilitates remote monitoring, making it easier to access data from any location.
· ‍Long-Term and Short-Term Monitoring: Whether you require long-term monitoring for years or short-term assessments, our sensors are designed to operate reliably without the need for maintenance. With a battery life of over 10 years, our system offers a sustainable solution for ongoing structural monitoring.
· High-Precision Measurements: Our sensors are known for their precision. For instance, our tilt sensors can detect movements as small as 0.001 degrees, allowing for detailed analysis of structural behavior. This level of precision is critical for applications like monitoring the settlement of structures, detecting minute movements, and assessing potential risks.
·  Real-Time Data and Alerts: The Resensys SHM system provides real-time data visualization and automated alerts. If the system detects that certain thresholds are exceeded, it can immediately notify relevant stakeholders via email or SMS, enabling quick decision-making and response.

Applications

Our SHM solutions are versatile and applicable to various types of structures, including but not limited to:
· Bridges and Tunnels:Monitoring for displacement, strain, and vibration to detect signs of fatigueor damage.
‍· Historic Buildings: Tracking environmental conditions like strain, potential cracks, humidity and temperature to prevent deterioration.
·   High-Rise Buildings: Continuous monitoring of structural tilt, seismic loads, settlement, and vibration to detect potential structural integrity issues.
·   Stadiums and Movable Structures: Monitors fatigue and stress to ensure the stability and safety of large, dynamic structures.
·   Rail or metro systems: Track movement, fatigue, and stress on rail system.
·  Steel structures: Track fatigue, corrosion, and deformation.
