Abstract

In this paper, the performance of shear structures equipped with tuned mass dampers and tuned friction mass dampers against near-field and far-field earthquakes and also under sine wave has been evaluated. For this purpose, four shear buildings were considered and dynamic analyses were performed on them in two controlled and uncontrolled modes using twenty far-field earthquake records and twenty near-field earthquake records and also under sine wave records. The results obtained showed that the response reduction in tall buildings is greater in far-field earthquakes than in near-field earthquakes. Also, the tuned mass damper has a better performance compared to the tuned friction mass damper in reducing responses. In addition, the selection of the type of desired responses is very important in obtaining the best values for the damper parameters; because it can yield different results in each case. Also, structures equipped with these dampers show better performance for seismic loading under far-field records.
