Abstract：The self-made shape memory alloy (SMA)-friction tandem damper was used to control the translational-torsional coupling vibration of the eccentric structure. The SMA-friction tandem damper can adjust the working status of the energy consumption elements automatically according to the seismic responses of the structure, and has such advantages as simple configuration and economical application. The motion equation of the eccentric structure with the SMA-friction tandem damper subjected to the bidirectional horizontal seismic actions was set up, and the time history responses of the structure were computed in program. Taken a six-story shear-type eccentric steel frame for example, the numerical results show that the damper arranged on the structure reasonably can decrease the displacements and the inter-story displacements of the center of mass of the structure, and that the torsional vibrations are controlled better. It is also seen that the damper can control the translational accelerations of the center of mass of the structure slightly, but change the torsional accelerations greatly.
