Abstract In order to use Active Mass Dampers (AMD) for the seismic response control of structures, excessive auxiliary mass displacements must be avoided even under a high level of excitation, which becomes a critical factor in the event of strong earthquakes. The control algorithm for the full-scale multi-story steel frame test structure at Disaster Prevention Research Institute, Kyoto University, takes advantage of a nonlinear control scheme based on a variable gain method to overcome this difficulty. The nonlinear control used in the test achieves effective use of AMD with a limited displacement range of the auxiliary mass for structures under various levels of seismic input. The structural control test is conducted to verify the efficiency of the variable gain control scheme when used with the full-scale test structure. The test result using a seismic record shows the effectiveness of the control method, especially when subjected to a strong earthquake excitation.
