Structural Health Monitoring
The implementation of Structural Health Monitoring (SHM) systems, when done effectively, offers agencies invaluable predictive insights. These insights not only bolster public safety but also lead to cost savings over the life cycle of infrastructure projects and streamline construction processes. By harnessing actionable data on variables like tilt, acceleration, strain, and temperature, authorities can make informed decisions regarding maintenance schedules, targeted inspections, and the structure operations.
WHY SHM?
Highly precise data afforded by SHM systems allows engineers to identify trends before they are visible to the naked eye, especially with long-term monitoring systems capable of detecting changes in structural behavior over time. These systems enable proactive responses to deviations from expected behavior, minimizing risks and potential damages.
Targeted SHM provides invaluable insights into structural behavior under various conditions, including thermal, dynamic, and live loading. By tracking annual thermal trends and long-term shifts in tilt baselines, SHM augments existing inspection and analysis programs, enhancing overall structural integrity and performance.
During extreme events, SHM systems offer critical real-time data on displacements, accelerations, and tilts, enabling engineers to assess structural responses and make informed decisions promptly. Additionally, monitoring moving components such as joints and bearings allows for early detection of anomalies, facilitating timely maintenance interventions and preventing costly damages.
Real-time information provided by SHM systems is particularly beneficial for owners of long-span structures, aiding in making timely safety decisions based on factors like pavement temperature and wind speeds at the structure level.
