Torsion in buildings has an important effect on buildings during earthquakes. For reduction of these effects, different strategies are presented. One of these strategies is structural control with tuned mass dampers. In this study, a passive tuned mass damper is proposed for the control of torsion in one axis asymmetric buildings subjected to earthquake. The stiffness and damping of this system are divided into two, subspring and subdamper elements, and mounted on stiff and flexible edges of the building. Results of the analysis of the building, subjected to seven far field earthquake records, show that the proposed TMD has a good ability in reducing the torsion of the building, especially a reduction in drift at the soft edge.
