Damping Of Seismic Vibrations Of A 3d Asymmetrical Building Model With Multiple Tmd’S, Jean-Paul Pinelli, Kai Chen, Hector Gutierrez, Rasvan Rusovici

Mechanical and Civil Engineering Faculty Publications

In this paper, the authors investigate the control of the seismic response of a three dimensional asymmetrical tier-building model, with a combination of three tuned mass dampers (TMD) located on the upper floor of the building. The 3D frame model represents a 3-story steel building designed for the SAC project in Los Angeles, California. All the dynamic analyses of the 3D structure are performed in ANSYS. The frequencies of the three TMD's and excitations are tuned to the appropriate fundamental frequencies of the model. The optimal number and location of the TMD's on the top floor are investigated, to reduce …
