Abstract
Abstract In long-term full-scale measurements at 4 steel stacks in Germany, the real vortex-induced cross-wind vibration amplitude collectives have been measured. With this real collectives fatigue calculations have been made based on the Eurocode ENV 1993-1-1, chapter 9 (“Fatigue”) and have been compared with the constant amplitude method of DIN 4133 (German code for steel stacks), which is similar to Eurocode ENV 1991-2-4, Annex C. In all cases the results of the DIN 4133 method are on the safe side.
