Cross-Fidelity Verification of Tuned Mass Damper Design for Slender Steel Chimneys: From 2-DOF to Solid Elements

A tuned mass damper (TMD) is the standard mitigation for the vortex-induced vibration of steel chimneys, yet it is sized on one low-order model and never checked at higher fidelity. We verify a TMD design for a 60 m steel chimney of 3 m diameter and 5 mm wall (D/t=600) across three fidelities: a Den Hartog absorber, a...
