ABSTRACT
Dealings with wind effects on long-span bridges comprise world-wide certain contradictions up to date. The presentation shows how Leonhardt, Andra and Partners looked for remedies. Methods to consider 3-dimensional effects are outlined and explained on the examples of the Sunshine-Skyway Bridge, Köln-Rodenkirchen Bridge and on bridges with low-frequent tower vibrations. A new buffeting investigation method under inclusion of nonlinear aeroelastic effects is explained. The method consists of a series of nonlinear time history simulations in the ultimate limit state. Investigation details are explained on the Helgeland Bridge and the Great Belt/Eastern Bridge. A short outlook on a methodical way to consider nonstationary flow-attacks is given.
