Influence of Excitation on Dynamic System Identification for a Multi-Span Reinforced Concrete Bridge
In vibration-based damage detection, changes to structural modal properties are tracked over time in order to infer the current state of damage or deterioration. As such, the ability to obtain reliable estimates of modal parameters, particularly natural frequencies and mode shapes, is of critical im...
