Reduction of Wind-Induced Vibrations on Industrial Chimneys

This thesis looks at dampers and passive aerodynamic fixes, using a 120-meter chimney as the main example. The chimney is made of glass fiber-reinforced polymer, supported by a steel lattice structure, and it runs into vortex shedding - an effect that causes resonance issues.

Wind-induced vibration reduction techniques applied to industrial chimneys to improve structural stability and safety.
Mitigation of Wind Vibrations in Industrial Chimneys

The study breaks down how vortex shedding works, simulates its behavior in RFEM 6, and tests different ways to reduce vibrations. That includes trying out a Tuned Mass Damper, a Tuned Liquid Damper, and even adding a helical twist to the chimney (with RWIND helping to check how effective that last option is).
