Wind speed measurement on bridges

In bridge applications it is important to monitor both wind speed and direction, however due to the height above ground it is often also necessary to monitor the vertical axis of the wind. This requires the use of a 3-axis anemometer. In these applications wind information is important to determine cable vibration, wind loading on vehicle traffic or structural twisting of the bridge itself.

Gill offers a wide range of 3-axis anemometers, which are ideal for this type of application. The WindMaster and R3 ranges both offer 3-axis data in robust packages, designed specifically to withstand the high wind speeds and harsh environments experienced in bridge applications.

Gill 3-axis anemometers have been used for many bridge monitoring applications worldwide, including: 

– The Millennium Bridge across the Thames in London where a study was undertaken to look at the three dimensional airflow across the bridge; 

– 3-axis anemometers are permanently installed on the Severn-road Bridge across the Bristol Channel; 

– The Tang Mai Bridge in Hong Kong, and 

– The Clifton Suspension Bridge across the Avon Gorge.

WindMaster 3-axis ultrasonic anemometers are ideal for monitoring turbulent airflow around bridges, providing wind speed, wind direction data and sonic temperature.

Research wind anemometer

The R3-50 3-axis anemometer has been designed for scientific research and is particularly suitable for determining fluxes using the eddy covariance technique.

WindObserver 70 2d sonic anemometers

WindObserver II is a robust, stainless steel 2-axis ultrasonic wind sensor. Capable of monitoring high wind speeds (to 75m/s), this anemometer is well suited to bridge-mounted installations.
