Effectiveness of Tuned Mass Dampers (Tmd) for Earthquake Protection in Chilean Buildings
Abstract eng: In Chile, several buildings have been provided with tuned mass dampers. They consist of pendulums located on the upper floor having a natural period similar to the building natural period. However, there are doubts about the real effect of these devices on reducing the motion of the building during different earthquakes. This work aims to theoretically evaluate the effectiveness of these devices. For this purpose, the influence of different parameters of the TMD (mass ratio, variation of period, nonlinearity, damping coefficient) and the building (linear or non-linear response) are analyzed. The movements consist of acceleration records from a database of 132 different Chilean earthquakes motions. Finally, the efficacy of a TMD in a typical Chilean building is analyzed.
