Bridges are vital components of civil infrastructure that must operate safely and reliably. Traditional methods for assessing structural health rely on the concept that changes in a structure's dynamic response may indicate potential damage. However, in the case of bridges, variations due to operational factors (like traffic loads) and environmental factors (such as temperature and humidity) can also contribute to these changes. This makes damage detection more challenging, as a bridge may still be safe while exhibiting changes in its dynamic response due to these factors. If the effects of traffic and the environment are not properly accounted for, it could lead to false positive alerts.
