Insight into coupled forced vibration method to identify bridge flutter derivatives
Xu, Fuyou; Ying, Xuyong; Zhang, Zhe;
 Abstract
The flutter derivatives of bridge decks can be efficiently identified using the experimentally and/or numerically coupled forced vibration method. This paper addresses the issue of inherent requirement for adopting different frequencies of three modes in this method. The aerostatic force components and the inertia of force and moment are mathematically proved to exert no influence on identification results if the signal length (t) is integer (n
