✦ Synopsis

A brief history of bridge #utter analysis is presented "rst. It is followed by an examination of a multi-mode procedure and a more comprehensive full-mode approach in aerodynamic #utter analysis of long-span cable-supported bridges. Particularly, when the span is very long and/or the structural sti!ness is not fully implemented, a combination of more than two structural vibration modes can have an important role to decide the #utter characteristics. Some numerical examples are given to show the e!ectiveness of the full-mode approach by comparing the results with those from the two-mode and multi-mode procedures.
