| Abstract | ||
| Tuned-Mass dampers, if well-tuned to a particular natural frequency, are an attractive solution in reducing excessive vibrations of buildings subjected to strong and unpredictable earthquakes. Two important parameters greatly affect the building seismic response are the input energy to the building and the dissipated energy of the structure. The optimum design is one that minimizes the difference between these two energies. This research aims to evaluate the effects of Tuned- Mass dampers on energy dissipation. Tuned mass dampers dissipate a great amount of energy. Without their existence, this energy would damage the building or disturb the occupants. Analysis of a ten-story reinforced concrete building with and without TMD using ETABS software is carried out. The tuned mass damper is placed on top of the building. The dynamic response of structures due to earthquakes is greatly reduced when tuned mass dampers are used. Results indicate the increase in mass of the TMD enhances the R.C building response to seismic vibrations. | ||
