“…This allows 3D representation of a line-like structure, considering an arbitrary number of modes, which are necessary for a proper representation of the dynamic behavior. The Pseudo-3D method was applied for the computation of vortex-induced vibrations of vertical steel masts [17] and the Niterói bridge [18], where the results were validated with experiments. An attempt was made in [19] to utilize the laminar Pseudo-3D method for to determine the critical flutter limit with few slices and as few as five modes.…”

“…Die Reduzierung der Bauwerksmasse verringert Trägheitskräfte, die einer übermäßigen Bauwerksschwingung entgegenwirken können. Wenn gleichzeitig die Dämpfung sehr niedrig ist und Resonanzerscheinungen bis hin zu „Lock‐in‐Effekten“ auftreten , ist es unerlässlich, schwingungsmindernde Maßnahmen zu ergreifen, um die Standsicherheit und Gebrauchstauglichkeit der betroffenen Bauwerke sicherzustellen.…”
