- •
A critical frequency ratio (Rc) is proposed for preliminary bridge health evaluation.
- •
Rc is a velocity and structural strength-dependent indicator.
- •
SPT-N value does not have a significant influence on Rc.
- •
Scour depth has a significant impact on the bridge frequency.
- •
Scour depth is one of the most essential factors for bridge safety.
