Abstract

Wind tunnel tests of twin box or tri box suspension bridge deck sections carrying wind screens reveal that the critical wind speed for onset of flutter is higher when set at a nose up angle of attack than at horizontal. The present paper reviews and analyses experimental aerodynamic derivatives available to the authors with a view to gain physical insight into the "nose up" effect and to assemble a predictive model for onset of flutter.
