PASCO-KENNEWICK CABLE-STAYED BRIDGE WIND AND MOTION DATA

This report presents wind and motion data for the Pasco-Kennewick cable-stayed bridge collected over a period of approximately two years. Objectives, in addition to the data collection, included processing to show wind turbulence characteristics, bridge vibratory characteristics and possible relations between wind and deck motions. The data reduction process is described. Wind data is formulated as spectra and coherence functions for three directions relative to the bridge. Acceleration spectra for the same winds are presented, and it is observed that acceleration responses are low (less than 0.01g) and sensitive to wind direction. The bridge fundamental mode shapes and frequencies are derived and shown to be consistent with calculations. Cable frequencies are also determined. Damping estimates are made for the deck and cables by the half bandwidth method. It is recommended that additional testing be performed to establish damping-amplitude relations for this type of bridge configuration. (FHWA)
