Considerable recent attention has been focussed on understanding the dynamic response of cable-stayed bridges and stay cable vibration, including rain-wind induced vibration. The Fred Hartman Bridge has experienced large-amplitude rain-wind induced vibrations that led to modeling efforts. To validate models of the stay cables developed from design drawings, a field test was conducted to determine the fundamental frequency of each of the 192 cables. This paper presents the field test, analysis of data and results. Comparison of results for eight sets of nominally identical cables in the design shows small fundamental frequency differences in sets of `long' string-like cables, but large frequency differences in sets of `short' beam-like cables and therefore a need for different test and analysis approaches for `long' and `short' stay cables.
