Management and correction of wind-measurement biases on long-span bridges
摘要
The wind measurements from bridge-mounted anemometers may experience speed and directional biases due to the airflow distortions induced by the surrounding bridge structure. The current work demonstrates a methodology for managing wind-velocity biases and provides recommendations regarding the placement of anemometers on bridges. The approach was applied to a set of wind-tunnel measurements acquired near a scaled bridge model. Wind measurements were acquired in smooth and turbulent flow, over relative wind directions of ±30
