This chapter deals with the basic principles of aeroelasticity theory (Theodorsen theory) and how these can be applied to bridge structures with sensitive deck shapes. The most common aerodynamical models with two or three forces as well as buffeting forces are briefly presented. Special effects such as galloping instability, torsional divergence and flutter are also presented. The technique of experimental design employing test results from scaled models is also described.
