Sensor Locations

Definition

Sensor locations refer to the specific placements of sensors on a structure, such as a bridge, to monitor its health and performance over time. Properly determining sensor locations is crucial as it directly affects the quality of data collected for assessing structural integrity, identifying potential issues, and making informed maintenance decisions. Effective sensor placement can lead to better understanding of stress points, dynamic behavior, and overall structural responses to various loads and environmental factors.
