ABSTRACT
This study presents a comparative analysis of field-measured wind data collected by anemometers positioned on the upstream and downstream sides of the midspan deck of Runyang Suspension Bridge. Considering the intricate aerodynamic interactions between the bridge deck and the wind, the disturbance effects of the bridge deck on the recorded wind data are systematically analyzed. Disturbed wind parameters are identified from the measurements, and their anomalous distribution patterns are investigated. To derive the actual wind parameters, a data-cleaning method is developed for mean wind speed and turbulence intensity. This method employs a statistical model to isolate the disturbance component and establishes empirical relationships linking the disturbed and actual wind parameters. The results demonstrate that the proposed data-cleaning method effectively mitigates the disturbance effects caused by the bridge deck, enabling more accurate evaluation of wind loads acting on the structure.
