A Comparison of Full-Scale Measurements of Stay Cable Vibration
As is now quite well known and documented, cable-stayed bridges around the world are commonly exhibiting excessive and unanticipated vibrations of the main stays, often associated with the simultaneous occurrence of wind and rain. This paper presents a characterization of the nature of these high-amplitude vibrations based on a comparative evaluation of data collected from the long-term instrumentation of two cable-stayed bridges in the United States: the Fred Hartman bridge in Houston, Texas; and the Veteran's Memorial Bridge in Port Arthur, Texas. Each of these bridges has exhibited high-amplitude stay oscillations. The contributions of various cable modes in the observed responses are investigated, and the influence of rainfall is discussed.
