چکیده
A study on the evaluating equivalent damping and response modification factors of frames equipped by Pall Friction Dampers is presented. To do so, buildings with various stories were considered. Nonlinear and linear dynamic time history analysis has been performed to evaluate equivalent damping for Pall Friction Dampers. Ground motions with various frequency characteristics scaled with Iranian earthquake resistant design code. In addition, nonlinear incremental dynamic analysis has been performed to evaluate the response modification factors. In this article, equivalent damping and seismic response modification factor for moment resisting frames with and without Pall Friction Dampers have been determined separately. The governing parameters were identified and their influence was traced and summarized along with implications for practical design. The results show that the equivalent damping of these frames using damper is higher than frames without it. Also we have this result for the response modification factors. It was also found that the number of stories have a great effect on these two characteristics of the buildings.
