The primary purpose of a structural health monitoring system is to monitor the structure to make sure that the structure will not fail.
Michael Chajes of University of Delaware says that structural health monitoring systems will help designate high stress areas that will be in need of corrective maintenance.
Utilizing a system to notify the agency of any areas that need corrective maintenance will allow the engineers that monitor the bridge to make any corrective action as soon as possible.
Monitoring any structure with an advanced AI system will provide more feedback on the health of the structure than by inspecting the bridge in person. This happens, because the gauges/sensors that are implemented in the structure when it is built will monitor every aspect of the structure while an engineered inspection can only be as good at the engineers that are inspecting the structure.
Structure maintenance systems are utilized by state governments to monitor structures that have had other failures. Our Interview with Jason Ardnt from DelDOT Bridge shows that DelDOT has implemented this system to keep the public safe.
DelDOT has one bridge in the state of Delaware that has a SHM system. This bridge is located over the Indian River Inlet, one of Americas top deadliest inlets. This bridge is monitored by the SHM system as it has previously collapsed multiple times and was rebuilt as current as 2006 due to the bridge being unstable.
DelDOT implementing a SHM system keeps the public safe from a bridge collapse since every aspect of the bridge is monitored with an announcement system that warns the appropriate people when sensors go above the allowed limit.
