This is an examination of the particular aeroelastic problems of cable-stayed bridges. The examination organizes the analysis methods around experimental flutter derivatives, and recognizes the full 3-dimensional complexities of the responding bridge models. The examination focuses upon frequency domain considerations. Examples are drawn from the analysis of the flutter and buffeting of twin-deck cable-stayed bridge in both completed and erection stages. Cable stayed bridges are considerably more vulnerable during construction than after completion. A note of interest is the manner in which the flutter derivatives delineate the different actions of the windward and leeward decks of the twin-deck configuration. It is noted how spanwise diminution in correlation of the flutter derivatives explains the experimentally observed increase of critical flutter velocity when changing from smooth to turbulent flow.
