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 two-degree-of-freedom non-linear model is used to simulate the behaviour of the structure equipped with a damper. https://www.pomyslnaszycie.com/laguna-3hp-c-flux-cyclone-dust-collector-on-sale/
