Fifty years have passed since the pioneering paper by Scanlan and Tomko (“Airfoil and bridge deck flutter derivatives”, J. Eng. Mech. Div., ASCE, Vol. 97, Pt. 6, pp. 1717-1737, 1971) first proposed the successful modeling of flutter and buffeting for long-span bridges. The model originates from the concept of Scanlan Derivative (SD), a set of empirically measured functions that physically describe the various features of the fluid-structure interaction of the bridge deck. This presentation examines the personal research experience in the field of bridge aeroelasticity of the author, by adapting and re-casting the SD modeling approach to solve two specific issues and to demonstrate its continued validity.
