EFFICIENCY OF ROTATIONAL FRICTION DAMPER IN IMPROVING SEISMIC BEHAVIOR OF STEEL STRUCTURES

friction dampers have been used for reducing the dynamic response of structures subjected to earthquakes or wind gusts. These dampers rely upon the mechanism of friction between two solid bodies sliding relative to one another rotational frictiondamper is a certain type of friction dampers that has several advantages. in studies regarding the use of rotational friction damper always efficiency of this type of damper was investigated in moment resisting frames.
