Experimental system for seismic response control is described. This system consists of a full-scale steel frame, shakers of active mass type and measurement system. An earthquake response generator system using shakers is explored to realize earthquake responses on the full-scale structure as if it were subjected earthquakes. On the basis of the modal control theory, an algorithm to control the shakers is formulated. After confirming the validity of the algorithm for generating earthquake responses by simulation analysis, this earthquake response generator system is applied into vibration tests of the full-scale structure. Observed acceleration responses of the full-scale structure in these tests are compared with calculated responses under the earthquakes. Results demonstrate the accuracy and validity of the earthquake response generator system. It is emphasized that by making use of this experimental system, the control performance of seismic response control on full-scale structures can be examined like shaking table tests.
