<P>PROBLEM TO BE SOLVED: To effectively utilize a damper for a building in normal time as well as at a time of an earthquake. <P>SOLUTION: In normal time, a damping force of a damper 74 is decreased to effectively attenuate vibration of a beam. When the measured vibration level of a foundation 28 is larger than a predetermined reference value or when an earthquake report is received, the damping force of the damper 74 is increased to effectively suppress vibration of a building 10. <P>COPYRIGHT: (C)2012,JPO&INPIT |
