- Abstract:
- This work is related to the structural and dynamic analysis of vibrations tested in a model of building-like structure which is armed by a three-story building with a Tuned Mass Damper vibration absorber. The structure it is connected to an electromagnetic shaker, which excited the support of the structure, provides forces with a wide range of excitation frequencies, including some resonance frequencies of the structure. The vibration absorber is a typical passive absorber known as Tuned Mass Damper (TMD), located over the third story building to reduce the vibrations. The overall mechanical structure is modeled using Euler-Lagrange methodology. The passive control is synthesized to actively attenuate the vibration system response via the TMD substructure, caused by excitation forces of earthquake acting on the base of the structure to improve the performance of the system and reduce the effect of vibrations. Some experimental results are included to illustrate the overall system performance.
