The vibration control research of MRE damper for the multi-level eccentric structure

摘要

For the characteristics of that the center of mass and stiffness centre do not overlap and that presence of translational and torsional vibrations under earthquake to the eccentric structure, MRE damper is used to control the translation-torsion coupling effect of eccentric structure under seismic action. Comparative analysis the structural vibration response in the absence of control and without control. Numerical calculation shows that the translational and torsional vibration damping ratio of the structure under the effect of control can reach maximum of 70.41% and 26.13% respectively. Thus illustrates the MRE damper for vibration control of eccentric structure is effective.
