| Abstract: |
This paper describes some of the research, initially sponsored by the Institution of Civil Engineers, into the mitigation of potentially destructive bridge deck flutter by the use of movable aerofoils, much in the same way that modern aircraft are controlled and stabilised by such aerofoils. Both flat plate and time domain analyses are presented, and the benefits offered by the movable aerofoils are quantified, using data based largely on the Humber Bridge deck parameters. The paper concludes with a proposal for a practical implementation of active aerofoil controls on the bridge deck along with a discussion on the way ahead. |
