Spectral Analysis of Chimney Vibrations

In the paper, the response of chimney in turbulent wind flow with use of the spectral method is investigated. The analysis is performed for wind flow model that reflects the real conditions. Numerical analysis investigates the vibrations of the chimney due to different parameters of turbulence. Spectra of longitudinal wind velocity for the numerical case, as well as the spectra of Karman, FSU are analyzed. The structure response for selected steel strengths and chimney cross-section reduction is analyzed. The frequency response functions for are performed.
