000022511 520__ $$2eng$$aAerodynamic derivatives are most often identified using bridge deck section models with free or forced vibration tests. With the use of a recently developed experimental setup, the motion detected during wind tunnel testing with a forced vibration technique can be far more sophisticated than harmonic oscillations. This allows one to overcome the most commonly highlighted issue regarding forced vibration testing techniques and to investigate wind-induced forces when considering realistic bridge deck motions. In this study, typical motions observed in buffeting free vibration tests are replicated in the wind tunnel by simulating a three-degree-of-freedom dynamic system driven by white noise. The experimental results show that aerodynamic derivatives identified during those tests agree well with the ones obtained when using standard forced vibration technique and are not sensitive to the motion applied.
