Simulated data of a bridge's ambient vibration being briefly overwhelmed by a vehicle (or similar live load) crossing it, and the FFT cleanly picks out the bridge's fundamental frequency (~1.5 Hz) plus a secondary mode (~3.5 Hz) — exactly what a structural health monitoring accelerometer setup is meant to reveal.
