Abstract: This research presents a study on the seismic assessment of steel frames with Rotational Friction Dampers (RFDs). The devices were used to protect structures from damage during earthquakes. In this study, steel moment frames equipped with RFDs is investigated under Nonlinear Time History (NTH) and Incremental Dynamic Analysis (IDA). Maximum interstory drift ratio is studied as Engineering Demand Parameter (EDP). According to the IDA curves, it is concluded that by adding RFDs, the behavior of steel frames changes from hardening phase to severe hardening phase.
Keywords: Rotational friction damper, incremental dynamic analysis, IDA curve, maximum interstory drift ratio, engineering demand parameter.
