A new industrial building was constructed for processing rough mining material, with sieves used for rock sorting. However, these sieves induced intense dynamic effects, resulting in significant vibrations. The building’s design did not incorporate dynamic assessments, leading to unbearable vibrations that severely restricted its operation. To address this issue, dynamic measurements were conducted to determine the building's parameters and its resulting dynamic response. As a solution, a tuned mass damper (TMD) was designed for the building's critical parts. The TMD parameters were optimized, and its performance was validated through extensive dynamic numerical analyses. Samples of these dampers were fabricated in the laboratory and subsequently installed in the building. The effectiveness of the dampers was evaluated through both numerical analysis and in-situ tests. These procedures demonstrated that the numerical model, developed using the Finite Element Method, accurately represents the system as a digital twin, including the building, dynamic drivers, and tuned mass dampers.
