Abstract
This work presents a study on the seismic assessment of steel frames with Friction Damper Devices (FDDs). The devices were used to dissipate seismic input energy and protect buildings from structural and nonstructural damage during moderate and severe earthquakes. In the Endurance Time (ET) method, structures are subjected to a specially designed intensifying ground acceleration function and their performance is judged based on their response at various excitation levels. In this paper, steel moment frames equipped with FDDs is investigated under Nonlinear Time History (NTH) and ET analyses. According to the NTH and ET results, it is concluded that by adding FDDs, the reduction percentage of roof displacement of frames will be decreased by increasing the number of stories. ET results show that FDDs have a vital role in energy dissipation because their hysteresis loop is rectangular.
