In this study, wind tunnel experiments were carried out in smooth flow to examine the nexus
between flow patterns around a flat-box section and its aerodynamics with the variation of
the wind angle of incidence (α). The model cross section closely represents the overall
asymmetric geometry and attendant aerodynamics of a class of flat-box decks frequently
employed in long-span bridges. To explore the flow around and associated aerodynamic
properties of this model that are distinct from a typical symmetric section (eg, rectangular) …
