Aerodynamic instability of suspension bridges
General linearized analytical theory for flutter of suspension bridge decks under uniform steady wind is presented; essential aerodynamic forces are presumed to be obtained, in real coefficient form, from wind tunnel tests on section models; problems critically examined include state of suspension bridge flutter studies, exact representativeness of bridge section models, general inapplicability of airfoil aerodynamics to bridge flutter, critique of forced resonance, autorotation theory, and D. Dicker theory as applied to bridge aerodynamic instability.
