Studying the behavior of asymmetric structures in past earthquakes shows that torsion was one of the main factors of failure of the buildings. One of the methods of reducing the responses of a structure is using energy dissipation devices. The main contribution of this study is determining of effective parameters and their values of friction dampers load to reduce the adverse effects of torsion in stiffness eccentric structures. For this purpose steel building models have been analyzed in OpenSees program for various stiffness and strength eccentricity and different distribution and properties of friction dampers. Finally the responses of the structure have been compared for different cases of damper distribution and change in effective parameters that influence suitable distribution and optimum slip load of friction dampers.
