​The behavior against wind of the actual bridge is shown as the combination of behaviors from each part including girders, cables, and pylons. Also, when the environment, in which the bridge is surrounded by, causes wind loads not only in the direction of cross longitudinal, but from other directions as well, and when the shapes of decks variate along the longitudinal direction, unanticipated wind-induced vibration from the section model vibration test may occur. The geometric and dynamic properties of aeroelastic model have to be properly adjusted according to the construction stages.

▣ Aerodynamic stability: Vortex-induced vibration, flutter, galloping
▣ Aerodynamic stability of full-bridge in the erection / completed stage should be considered
▣ Aerodynamic stability of full bridge in various wind directions should be considered
▣ Topography effect should be considered
▣ Effect of construction facilities (eg. Derrick Crane) should be considered
▣ Vibration control methods such as wind cable and TMD should be considered
