Investigation of the Dynamic Behavior of a Chimney at Tripoli-West Power Plant

This paper investigates the vibration behavior of a chimney at the Tripoli-West power plant under wind loads. Finite element models of the chimney are developed to analyze the existing chimney structure, and assess the impact of repositioning the supporting rings typically used in such chimneys. Both free vibration modal analysis and forced vibration harmonic analysis are performed using ANSYS software, considering the wind loads in the area. The final recommendations focus on the vibration response and the influence of the supporting rings and their locations along the chimney, aiming to mitigate undesired vibrations and structural fatigue problems.
