ABSTRACT
The interactive wind-structure dynamics of long-span bridges are considered in an analytical framework the basic parameters of which are extracted from minimum essential wind tunnel experiments. In these latter the bridge deck section model plays a central role. The process employed emphasizes the important mechanisms involved and is intended to elucidate those necessary steps to be taken to develop realistic information for design. The relation of this approach to more empirical approaches is discussed. A number of related efforts reported in the literature are documented.
