Modal Estimation of Civil Structures Subject to Ambient and Harmonic Excitation

In this paper addresses the problems of separating structural modes and harmonics arising from sinusoidal excitation. Though the problem is mostly know in mechanical engineering applications such as rotating machinery, some civil engineering applications experiences the same challenges. A robust and fast harmonic detection procedure is presented and illustrated on a civil engineering case.In this paper addresses the problems of separating structural modes and harmonics arising from sinusoidal excitation.
