る。SUMMARY OF THE INVENTION For example, honeycomb dampers such as steel dampers (for example, Japanese Unexamined Patent Publication No. 1-190880), joint dampers (for example, Japanese Unexamined Patent Publication No. 63-2199926), oil dampers, dynamic dampers, viscous dampers, and the like are available. is there. Since these are passive types, the damping effect is also natural damping. Instead of this, the method of measuring the response of the ground and the building by the sensor, calculating the control force from the result, and generating the control force to the device properly arranged in the building to perform the seismic control is called active seismic control. Therefore, compared with the passive type seismic control, the seismic control acts more promptly and surely, and highly effective control can be performed even for uncertain earthquake motion.
