Tuned mass damper (TMD) device has been a popular vibration control system for moderns as high-rise building, bridge to suppress excessive vibration due to environment or human loading. Moreover, multiple tuned mass dampers have received much attention in the researched. An optimal design theory for bridge implemented with multiple TMD devices is proposed in this paper. The proposed method chooses the objective function with the constraints on the peaks which are at the same heights over frequency ranges of interest. This proposed method successfully reduces vibration of bridge traveled by a car. In a future study, we will extend the optimal design theory for the cases with more than one car and the bridge under seismic loading.

Tuned Damper

<p>High-rise buildings are progressively being designed and constructed in increasingly slender and complex shapes. Consequently, excessive wind-induced vibrations of these structures are a growing serviceability concern due to their flexibility. Tuned mass dampers (TMDs) are regularly incorporated into high-rise buildings for mitigating excessive wind-induced vibrations. However, traditional TMDs are only effective over a narrow domain of frequencies, require an immense mass and occupy a significant volume of interior space. A novel modular air-tuned damper system was developed which is more cost-effective and flexible in distributing its mass throughout a building to make efficient use of unused space. Importantly, the air-tuned damper system is capable of being tuned across a broad domain of frequencies to more effectively alleviate wind-induced vibrations. This paper presents a case study demonstrating the performance of a high-rise building under 1- year and 10-year wind events whilst equipped with the air-tuned damper system. Dynamic analyses were performed for evaluating the reductions of the building’s lateral accelerations considering different air-tuned damper configurations. The performance of the building under the different damper configurations is discussed.</p>
