Karman vortices observed around chimneys may induce dangerous structural vibrations at certain wind velocities.The aim of this paper is to analyse the effectiveness of a pendulum damper in reducing vibrations of a steel chimney.A PLUS EPA two-degree-of-freedom non-linear model is used to simulate the behaviour of the structure equipped with a damper.The results of the study show that the use of a pendulum with tuned COQ10 300MG frequency leads to significant reduction in structural response.
